Playing the Beta at the moment obviously.
I am hoping that at some stage the gains from levelling will be tweaked. I find that I am just putting points into essences and health because the benefits from increasing the others are just too small in relation to these stats. Essences means more cities more strageically placed, and health to survive, because for 1 level to increase attack by only one point with no gains in health is not much fun.
I guess if you gained a stat bonus to health and mana on levelling that would help a fair bit I Think. In saying this of course, I don't want heros to be unbeatable in the higher levels (I found that I could do that in MOM with artificer and making Uber items for my heros... 1 hero could win the game), but still I would like to see a better balance on levelling up. I thought I might be more intested in popping those other stats up, if it was a 0.2 gain, and not a 0.1 gain per point.... maybe...
Just another thought / thing to look at. I am assuming this sort of balancing to be going on in beta 3.
I am guessing that this has been looked at, but at the moment, I can't seem to find the topic / forum item discussing this.
