pretty much as the tittle says which is better all around Pk 2v2 Tw ect ect ....
really depends on your preference in tw tbh.. Do you want to cause loads of damage? (wiz) Do you want to heal your whole squad/Buff your squad/ Keep everything from dying? (cleric) Or do you want to have a mixture of DD/Heals? (Mystic) These 3 classes are good and wanted for tw.. So it really depends on what you want to do in tw/pk so you could be entertained.
Go with mystic if you want overall power. Their heals are very usefull in keeping people alive and with the attacklevels now affecting Absorb Soul they have the most reliable high-damage attack in the game. (Vs arcanes.) With decent regular damage and a very effective debuffing-pet against melee they are also pretty good at taking out LA/HA classes. That being said.Wizards are better at sending light or heavy armor classes on a 1-way trip to the floor but not quite as good at taking out arcanes. Wizards are also not as survivable as mystics but still a bit harder to stunlock in mass pk (Due to arcane defense.) which is arguably a better point for survival. Getting purify on the mystic bumps it s survivability well above any arcane but does bring it's damage down considerably. Switching weapons can negate a lot of this though, but that goes for all classes.Clerics are the absolute best at keeping people alive. They're also pretty mean in a self-buffed 1on1 but completely horrible at killing anything with buffs. Nothing can beat their ability to aoe buff and heal plus their varied ability to immobilise, seal, sleep, purify etc but out of all the classes they are probably the worst at killing. (Except for maybe a vit barb or a hybrid HA/AA veno.)
Soo 1v1 mystic v Wizard which would win lol both sound pretty gd
