1v1 generals aren't too hot except for certain matchups and counters (like Oak to counter Rook).  However, in a team game I always would rather have around 50% of the team be generals rather than take on more assassins.  I have been in many games that were 3 assassins vs 1 assassin + 2 generals and the team with the 2 generals wiped the floor with the all assassin team.

I used to play a tower rook and actually found it very useful for pushing, but he doesn't score nearly as many kills as a hammer slam rook.  Lately I've been playing a more hammer centric build but mainly to get a feel as to how to counter it, not to win.

I can say only that the opposite has been my experience.  Unless you're talking about Oak...I do think Oak can be useful sometimes.

idk ive had games with all assassins vs a mixd bunch but never assassin vs generals alone, in all the games ive played it never was the character the person was using but the tactics and skill they used. generals can become just as powerfull as asassins with some items, but assassins dont need to spend money on the units like general. i always choose monk of the bat,playing a general. and then ranged units,
(Makes sense i play a melee general that spawns melee units when killing enemy muhahaha)

Also the favor items deffinitly play arole, some can give a nice edge over the oppenent.
and i think the main prob isnt the char alone but paird with what items makes it seemingly OP to alot of people.

i will support the Rook is prolly most user friendly though.

Into release I'm gonna have to go with Generals - I'd say Oak or Sedna are most OP right now - especially with minion stacking.  A DPS Oak with 3 levels of priest minions can go toe-to-toe with a DPS UB and walk out with full health (!).  Alternatively he can get 3 levels of siege and walk out with half health but it only takes a couple seconds to kill his target.  With 6 siege and 6 priests a level 10 Oak can take down one entire *side* of your base fortification on Prison in under a minute.  That's about 8 seconds a tower.    

Only played 1 v 1 and not against AoE though, so we'll see what team games look like. 

Mulitiple Reg. teams make me cry...

Snipe x?, with tracking... Don't drop below 50% or arrows will fly from all over the map. Some maps you can't even make it back to the base before snipes come flying even if it was the snipe that dropped you low in the first place.

Not really complaining, I used Reg. til this new tourney, then chose Darkness

Still learning them mostly.

I'm kinda noobish but I've noticed that the rook and TB seems to be the most powerfull ones but if you're fast enough the rook will never ever be able to catch up with you so if you play TB you can run around and use Firebolt on him, if you get to close he's dangerous tho

regulus bit  op against tb in prison heres why

imo i believe he is a bit op in a map like prison against tb. Tb has low health and u cant win regulus at lower lvls if he go angel build, he can attack tower very early and generally almost anihilate u in 1v1. The only way is to try to gain xp from creeps running in another path from him till u have a high dmg shatter but that is not easy at prison since there are no empty spaces or walls in middle so he can reach u very quick and if he has slow .gg.

but i believe items that stucking items makes any demigod a kit more powerful and unbalances his role. because u stuck armors and have some high dmg/high armor demigods and that doesnt seems right imo
