Well i would like a lot of skills to choose from, but only few to actually use so you can individualise your character.
What is really important is that the skills have synergies when used (i.e. combos), so that spamming one good skill will get you nowhere.
Whatever they (the devs) do the result should be:
(i) Unique Demigods (i.e. unique to each others but also unique to their opponent controlled "clones")
(ii) No useless skills
(iii) a lot of possibilities to plan around each demigod, that means skills and equipment (i.e. min/maxing)
(iv) No spammable skills, have variety, synergies, combos ect.
Oftopic: Many complaints about the dota Heroes arise from the way Warcraft 3 attributes work (i.e. int, dex, str) and i hope that Demigod won´t go in that direction.
