mmmmm, mana flare and dust storm are hilariously strong in bigger games... anyone testing 3.1 knows.. but in 3.0 it still works. In fact, we played a 5v5 today, and the other team got mana flare.. raped us! it dealt more damage than anyone on their team!
dust storm also... have your allies go avatar, and you channel dust storm.. they can rape your opponents. the problem here.. is that YOU cant rape... so generally, players want the kill; not the "nice teamwork".
Banish is amazing... if nothing else, it is a kick ass CC. best CC in the game, really. 7 seconds at max level, like 15 second CD... works great to focus fire 1 guy at a time.
defend, combined with MS, is beyond OP.... Other than that, it is decent if you are using an armorless build... really, main leveling it with a pretty specific armorless build wouldnt be bad at all.. you could focus everything on damage and slaughter, up until late game.
mana burn is actually in the builds of the top 2 players right now :-p It is reallly good; because it is a kick ass nuke, AND it rapes your mana. 90% of builds use mana... Without mana, you have no build. On top of that, it hurts! Not a lot more needs to be said about it.. i actually hadda nerf the CD in 3.1 because this skill is REALLY strong! Especially with a WW item...
Dragon punch is under used.. but on battlemage with restore mana or absorb mana, you can farm with it and hit 8 for first duel.. then deal 600 dmg a cast for first duel! Come on, that, WW, and restore mana... dear god!
goblins is under used; yet with a slow ward and some fast creep spawns, you can hit 10 for first duel with them! I have hit 11 a couple times with them.. but it was more luck based.
dread ritual is under used... but in bigger games i have gotten 4 kills with a single cast before... the CD is really low; and when in doubt, you can clear half a creep spawn in 1 cast too.
Hmm, Tornado? You kidding me? This skill rapes! yet no one uses it. It can clear a spawn twice over with its duration; CC opponents, and deal huge AoE dmg while slowing... Not a lot more to be said here...
badger, has chain heal, taunt, and soul link.. not to mention the shit ton of armor and HP.
Watery defenders... Ever link your team to these guys? they can tank fire boss for you, without you taking a single damage.... It is like a free 20K HP for your team if you link to them before duels...
