Rogue is nice, right, but there are nearly no skills which fit to the warrior. I don't wanna play a rogue as second option, I need more skills/buffs for my main class. Only Stealth sounds really sexy (rebuff warrior shouts after switching weapons
Warlock? Any benefits for a warrior?
Bard: Speedbuff, Manareg and Noise! Noise isn't the most important buff for a tank and useless in PvP. Manareg for a warrior needed? The speedbuff is the only HUGE benefit, right! But nearly everybody goes Bard second (my buffy too) and I like to party as european.
The Clerics heals aren't great without an int-build and the stats-buffs for party-members goes away when switching to my sword. Resurrect and Holy Spell are great!
Last but not least the Wizzard: No nukes as pure strengh, I know. There are 2 interesting skills:
Invisible - Shorter duration than stealth, but fewer detection-skills against invisible too. And group invisible sounds perfect for a party.
Teleport - Very rare, an active skill without a specific used weapon! A melee fighter who can teleport on the battlefield, I like it.
Nobody else likes Warrior / Wizzard?
My favourites are Wizzard and Cleric, but Rogue and Bard looks reasonable too.
