Not sure I've seen any post speculating on the gameplay of gunbreaker (GUN ?) itself, so here I go.
I'm simply asking what you people expect for this new tank. It can be anything, I just want to kill time while I wait for it.
I'll give my personal list (can be long). Before I begin, let me just say this : I think this expansion is the one where SE tries to create really different and new things. Between the areas and races, all the way to the jobs. I think (and hope) GUN and DNC (if it come as heal) will be very different than the already existing one : melee healer for DNC and... different tank for GUN, leaning toward a DPS style. Why I think that ? Because it's something people ask, if I'm not mistaken, and because we already got 3 tanks and heals that feel sometimes too close to each other. There is no risks to take by creating something different.
So, now my wishes :
First, the most important. Since GUN is one-handed with no off-hand, make it fast. Like SAM for example, with a buff. Either refreshed by a combo, or better, by using one or more of these ammos we heard about. Either way, we need a fast tank, we already got 3 of them that are slow af, as a NIN player, switching to PLD feel like dividing the speed of the game by 2. That alone will make me play GUN a lot, probably even as main.
After that, what I wish the most is for GUN to have a rotation that is more complex than other tanks. Ammo management looks like a good idea already, I hope there is one that give/refresh a buff (speed plz), one that put a DoT if it's not on another combo already, probably one for mitigation, one or more for a big damage cd that you have to plan and use on cooldown (Tempetus Est, the cross-shaped attack ?), and other used as dump (simple explosive slash ?).
I think giving all of that will reduce it's utility, but I don't picture myself how a Gunbreaker could have some sort of utility. Perhaps one ammo can be shot on a ally to shield him ? Making it a good OT to help mitigate TB. What other utility can you imagine ? I'm dreaming of a dps utility but let's be honest : giving a rDPS cooldown to a tank will make it mandatory in any composition, so I can't see that happen.
Last, the LB3. I'm pretty sad we won't see any offensive LB for GUN since Squall and everything, but what do you guys imagine ? Maybe deploying some sort of advanced turret that creates a big barrier around us ?
Voilà ! That's just my wishes, but I think GUN is the good job for an offensive, complex tank that borrow some concept from DPS. Since the GUN tank or DPS question was so important, maybe it's the good idea. This will probably attract a lot of DPS, myself included. Make DNC a melee heal then I'll stop playing DPS I guess
Feel free to answer my expectations, give yours or ignore my post ! (or everything ?)
