To be honest, thm and con seem to play nearly identical. They have copies of each others abilities with different colored icons and damage types. Ask yourself would you rather have buffs or debuffs and chose from there. IMO, debuffs such as poison dia bio slow are nearly useless in this game whereas buffs are somewhat useful.
Debuffs, nearly useless! - poppycock!! lol seriously though the THM debuffs are worth it, just ask my tank in my (sort-of) static party - slow actually slows down the attack speed of the mob, Dia actually decreases the mobs def, Bio actually lowers the mobs attack damage, Absorb Def actually decreases the mobs def and increases mine (not useful to me in a party though;). Poison's dot is fairly good too but I wouldnt use it and haven't done for a while when there are better spells out there to help other party members. On the other side I find that CON's tend to use Shock Spikes and Stoneskin as buffs for party members (what are the other ones?), however Stoneskin is pretty useless unless you are fighting a leve mob that hits hard and you want to take down fast with as little damage as possible - two hits and its over, although if the mages have it on it can be useful in case they get agro (which they never should!). Shock spikes are very useful unless you are in a party that wants to make SP for everyone including the mages - slowing the mob by stunning it means less atacks, which means less damage on your tank which means less sp for the mages when curing. Of course the same arguments could be made for the debuffs as well. Edited, Oct 24th 2010 5:52am by EdyNOTB
