I don't know, man, maybe in pvp this class is that bad, I don't pvp in this game. But in pve content my only concerns (as sentinel) were lack of threat generation and lack of hard taunts. First is fixed in next module (I hope), second well maybe someday... I'm not a pro gwf expert, but never had real problems with damage…
1. You gain divinity fast enough 2. Casting times add "skill check" component to the gameplay and they were reduced enough in module 5 3. Righteous feats are fine, you don't need neither another debuff through feat tree nor astral shield weapon damage stuff
How about making temp hp to be dependent on hp at the moment you use unstopable? I mean less hp you have when you press tab - more temp hp you will get as a result?
I like trinity based games and I hope Cryptic will make 1 tank and 1 healer to be required in epic dungeons. Seeing that paladins could be either tank or healer, as well as changes to lifesteal and regeneration I...well, really hope they'll do so.
