To me, Rook, UB, and TB are the toughest.
Rook has massive damage through Hammer and Towers, and stun is extremely useful.
UB is very fast, so is hard to get away from. It's also quite easy to load up health and armor while keeping dps on him, plus he has life drain stun and ranged dot.
TB has relatively easy to pull off shatter combo.
Staff of Renewal is crazy for Rook and TB. Warp is incredible for all Demigods, but it really shines for Rook and TB.
Have to agree with that.
Most OP (In Order):
The Rook
Ice TorchBearer
Unclean Beast (to a certain extent)
I can really safely say that the Rook and Ice TB are "overpowered". The thing that no one has really exploited with this Beta is the Rook's towers (at least not exploited as much as they can be). They can really be a huge pain in the *** and very, very OP if someone goes a tower heavy build. On top of that, his HP can get pretty ridiculous. Once he gets a warpstone he can almost 100% guarantee a hammer slam hit on target. Whith Rook you get minimum input and maximum output. Basically, put in a little skill, and you get huge damage.
Ice TB's shatter combo just does too much damage imo. He can 1v1 a lot of Melee Demigods pretty easily once he has reached the stage where he can do his shatter combo effeciently.
Unclean Beast...well thats pretty debatable atm. Dont think we can say for sure if he is overpowered or not.
Regulus.
He needs no skill and you kill most characters with one click.
I mean hes not even very fragile so you could justify his range and dmg....
Snipe is the killer skill, and needs no skill to use as well.. best finisher.
Saying he kills people with "one click" isnt an argument. In fact, ANY Demigod can kill with just "one click"...lol. Its not hard to make all Demigods sound that easy to use - e.g. "With UB you just click and they will eventually die".
Regulus is definately very fragile. One of the most fragile DG's by far. Of course if you let him get the high end items this isnt so true, but thats the same with every Demigod.
You forget to mention Regulus's need to tatically lay mines and lure enemies on to them - his hit and run vs melee Demigods in a 1v1 (which isnt so easy to pull off as "one click" - his use of snipe (trying to position yourself as far as away as possible so snipe does more damage and making sure if the enemy is on low hp your Snipe isnt on cooldown). So much for your one click theory. He is however a strong Demigod

I like this thread - interesting.
