Yea ... I just feel that most features are too simple or too primitive at this point. Especially with combat (and apparantly Hairrorist agrees).
Honestly I'd rather have the "traits" (like adventurer, Warrior, Thief, Warlord) be actual "classes" ... but for that to have ANY meaning at all, I feel that combat should be a bit more complex. (like having a bell-curve/ Gaussian, or separating attack/defense and damage).
Honestly I feel the more "combat stats" the better (that perhaps automatically increase at each level up, at different rates depending on Champion and their class). Like an agility score which can increase your chance of randomly dodging an attack, or of randomly having an attack/counterattack cost less action points (leading to multiple strikes). Or having an accuracy score that affects only attack and not damage. Or having a power score that effects only damage and not attack, or having a crit score which effects your chance of getting a "critical hit" (or a skewed Gaussian even). However, if its a skewed Gaussian then that could probably be its own stat (maybe tacked onto accuracy, or perhaps be called Focus), with a crit score itself merely give a chance for a 1.5x damage, or a 2x damage ... with no effect on attack rating, just a chance for extra damage.
also perhaps a luck stat that slightly effects crit rating, agility, and accuracy ... and perhaps Focus as well.
Also, maybe constitution points can get more powerful as your champ levels up. Like at level 1 each Con point gives 1 + 1/5 HP. At level 2 each pt gives 1 + 2/5 HP. at level 5 each gives 1 + 1 HP. At level 10 each gives 1 + 2 HP. So a 10 Constitution guy at level 1 gets 12 HP, while that same guy at level 10 (still with only 10 constitution) gets 30 HP. Of course, if you wanted HP to scale faster, you could increase the rate at which HP gets stronger. Like say 1 + X/3 HP, so that the HP roughly increases 100% every 3 turns instead of every 5 turns. And that's just the simplest idea I could think of (well, at least the HP stuff)
If all of these changes were made (accuracy, agility, crit rating, focus, and luck increasing at each level up, at rates dependent on class ... as well as HP scaling based on level) then I think Champions could be made much more interesting.
