I'll start off here by admitting that i'm still quite new to the game, new to tanking, and new to mmo's in general. Reading advice from more experienced tanks on these boards has helped me make it to where I am, so in all likelihood I'm "preaching to the choir" here, but here goes...
I main a paladin, but because I enjoy a slower progression, crafting my own gear, etc, and tanks seem to level crazy-fast so I also have a Whm. Both are at 40 for now. When I heal, I've noticed a trend (a growing trend?) of gladiators and paladins not initiating their pull with shield lob. Instead, they saunter up to a random piece of trash, auto attack, wait for the mob to slowly convene on them and then start spamming flash. Sometimes, they even stop flashing after only one and start their RoH combo.
(It should probably be noted that I have not encountered this problem with marauders and warriors because they have Overpower, and well, it is awesome, but I digress...)
This method always seems to cause problems for the party. I have to wait for the trash to convene on the tank so flash will encompass the entire mob. All the while they are taking hits, so when they've finally generated enough hate that a cure doesn't pull them, I can barely pop cure fast enough to keep them up. DPS is always pulling hate no matter how carefully they attack. While these problems are nothing but obnoxious in the very low level dungeons, when I hit Brayx LS and higher they caused some major issues.
When I tank I always pull with shield lob, and here are a few of the reasons why:
1) I have far more control over where the engagement takes place -
a) By using shield lob, I can make the mobs come to me, as opposed to me picking a piece of trash and engaging it at it's location.
b) This also helps the mobs arrive at the point of my choosing closer to the same time. I know we're talking about seconds and half-seconds here, but doesn't every difference make a difference?
C) I don't waste precious Flash MP trying to pull trash that is not in the Flash AOE. This always seems to contribute to the GLA or PLD running out, or running very low, on mp throughout the battle, sometimes when it really counts. If I Flash after the shield lob pull, my Flash hits the whole mob and gives me maximum mileage for the MP I spend.
d) Though I haven't gotten to the point of doing SR's yet, my reading suggests that point b) and C are even more important if I'm trying to pull several groups to a single point. I have to get the mobs where I want them long before I start spending my limited MP on Flash.
(I don't know if CoS alters this strategy since I don't even have it yet, but I wouldn't think so. Please weigh in with advice or corrections if I'm wrong.)
2) When I shield lob I generate first-strike enmity, at least on target #1 -
a) Even if we assume that I don't take the time to mark target #1, DPS can easily see which target takes a shield-lob to the clavicle. This allows both DPS to focus on one target that has taken a significant enmity strike from the tank. As DPS moves to engage, the tank's gcd finishes and the flashing can start and the healer can start healing, or regen, or even keeping up stoneskin if the tank has high enough HP.
b) While the DPS is working on a target that already has good threat generation, I can move into RoH combo and use RoH finisher on target #2, #3, and/or #4 and all but cement myself as the enemy target. (peppering Flash in between Savage Blade and RoH, of course)
c) Even if DPS decide to open with AOE, I haven't wasted MP on the pull, the mobs are safe within flash range, and I can flash once to offset each of their AOE bursts. Then, because of the lob, they can move straight to target #1 and still not have to worry too much about pulling hate because of the first-strike enmity I gained.
3) It's practically free -
a) By the time the mobs convene (because you are in control of where the engagement happens), the gcd is finished or almost finished.
b) because of a) You can Flash right at the first hit, or even before.
c) by the time you're done Flashing, half or more of the TP you spent on the lob is back.
Now, none of this is to say that overeager DPS and healers that cast before the pull don't still cause problems. But I don't understand why a tank wouldn't at least try to find a place in his/her toolbox for all of his/her tools. Shield Lob has always served me well. It makes things smoother, imo, and unless I derp! I very rarely loose aggro. Also, I'm not saying that my way is necessarily the right way, or the only way to tank. I understand that some people may only be running a GLD or PLD for the bonuses, or to pick up cross-class skills like provoke. But even then, I just wonder. Why not?
Have others encountered this when playing other classes? Am I just having bad luck? Or am I just wrong about my assessment of Shield Lob? I'd love to hear what some of you have to say.
