With Drogan the Dwarf (the Tinkerer's hero), when he gets a certain beast skill his damage halves.  This might be because the game is seeing "does 50% damage" rather than "does 150% damage".  Anyway, maybe something similar is happening with the ranger.

Do you intend to release a smaller fix for the minor bugs (not a beta 5) or will you wait until beta 5.

Regarding Beta 5

Will we see revised skill trees for the remaining sovereigns (guardians, priest, commander, tyrant, wizard) and their heroes. I still think that ex. Varda is kind of weak compared to Drogon.Likeweise with Peregrin (although I havent tried him since Beta 2).

Will we also see revised spell description, effect and cost. I still do not understand why Fallen Star cost 150 mana (and this is an increase from Beta 3, 134 mana). I mean it deals something like 18 damage plus something x*Shard, while Pillar of Flame cost 10 mana and deals 10 damage + xx*shard.

Do you want suggestions/improvements for the sovereigns and heroes? 

If yes, would it be possible to get some insights into how the Stardock sees the wizard for example: purpose, what feeling should the player get when playing wizard vs. guardian.

For example do you see the wizard as the stereotype wizard with a filt hat, gray beard and a long white staff, or more like a warlock type. Do you see the wizard as a sovereign, who should be focused on magic (better spell casting, better spell resistance, better/more/advanced spell, better mana gathering, better overland/strategic spells etc. )
