Variety is the spice of life, while some times armor/weapons may look stupid you can now glamor them if you don't like them or be happy you have options. What YOU don't like someone else might.
You're asking for an aesthetic change really, while I agree shields is slightly silly, a staff with 30 int should be no worse or better of equal level of a wand with OH of 15/15 INT for example. THe same complaint about your robe head problem, it's all an aesthetic problem, the stats by comparison I noticed are the same when it comes to equal level headpiece vs no headpiece options.
Spells cancelling from movement is a classic choice, it "breaks" your concentration and as a result your spell is reset. There was a time when we played games to have this thing called immersion.
A. Learn to handle your controller better.
B. I never had this problem as severe as you make it out to be. Could this be the result of answer A?
C. If you're pulling aggro it's not necessarily the Tank's fault, maybe...JUST maybe, you should be watching YOUR threat generation. If you're letting the Tank do their job first those 3-5 seconds you sat back to let them get threat will not interfere with your life long enough to cause issues.
D. I think I have experienced this too, not sure if it's a server/client problem or in-game issue.
E. A minor annoyance, again can be avoided for the time being because you should be able to anticipate monster death especially for Trash mobs before you get so invested into an attack.
You're right, it does suck. No issues here.
This is core game design 101, learn to get into a Static or dedicated FC or find friends to play with, this will never change, if you don't know your role and what you're doing in content in this game, guess what. You will die.
I agree, limiting post size is ridiculous.
It used to bug me, but just dismount, they did post why they do that at some point and I can see when it would be rather stupid, I wish for it sometimes, but I don't necessarily pine over it either. As for swicthign classes, I play with a mouse/keyboard, these problems don't exist for me like they do for you. Did you know you can drag your different classes from your character panel into your hot bars?
This is sadly something that will come over time. There's nothing they can do about this within 30 days to satiate everyone's appetite.
I can empathize with your annoyance, but really? This is not really a big deal, I may agree with you that getting slowed for 30 seconds is annoying, but did you know mobs have line of sight? most you can walk behind and avoid aggro.
This is a latency thing I am pretty sure, I can do both, I can complete casts at certain points in the bar and move and other times I get the latter. Great for healing Titan sometimes when you know you can complete the heal at x% of bar completion.
