Just a quick write up of some things in this game that I dont think are fully balanced.
1.) The strength of health items to other items... Im not just talking about armor items either but all other items. Even the most cost effecient +damage items and utility items just dont stack up powerwise to health items(this has been proven numerous times imo with stats and math by other people, even disregarding the simple fact they dominate in game). As such you really have very few good options to choose from which limits variety a great deal imo. imo the +damage items should be either % base or give better bonuses. There should be items that strictly give health regen like +30health regen this would make armor use more effective because armor becomes better with health regen. I think most to all your best/experianced players will agree that a lot of items simply are sub-par and not worth using... this includes favor items. IMO simple fix would be to tweak the weaker items, problem solved.
2.)This is a team/clan game with no way to form teams, group up with teams, organize, talk, compete... basically no sort of team/group support. Something.. anything would help this out a lot. If not just a way to form chat rooms or talk to other people outside the lobby to group up and discuss playing against others, strategies, forming games ect.
As it is now there is really no way to balance the game in-depth because no one is really playing the game competively against others with fixxed strategies... the meta-game is not established so there is no way to determine what is the best in the meta.
3.) Demigods
Queen of Thorns.. and no just because she can be used to fill a roll does not mean she isnt underpowered. You can say I dont know how to player her right.. ok w/e lets assume you are right.. then how come out of all the matches Ive played Ive yet to come across a single QoT player who was badass? This doesnt ruin gameplay as anyone can simply choose not to play her.. but c'mon
Sedna heal is too powerful but besides that shes pretty weak. Makes her playstyle 1-dimensional
Fire Torch Bearer targetting and attacking moving people is bugged/annoying. Even if you dont want fire TB to be able to autoattack moving people(which I dont think there is a reason for) it shouldnt be as annoying as it is now. Aka if you target someone with fire tb you automatically go as slow as them even if they are snared -60%. You also stutter a lot. its just an annoying feature if it is a feature to begin with imo.
Frost Torch Bearer. Most skills are underpowereds. And this goes for other demigods too(especially QoT) some utility skills are just insanely over priced(mana cost) for thier effectiveness. Like Frost TBs power that freezes/stuns everything around him, sure this can be effective for rushing towers but it takes so much mana and doesnt even last that long until trained up its just too much of an investment for a pretty useful utility spell. On top of this while you can play a fire tb, pure ice tb just doesnt pack a punch. Frost Nova should cost a lot less mana straight up or do damage. Also since frost TB doesnt have a lot of damage spells his base auto attack damage should be higher or his damage buff should be permanent not wear off fast.
thats all I got right now. ^^
