1) the way we get stat cards FOR FREE atm in void, you cannot blame P2W... and heroes should be a large part of this game. so i think its fine the way it is.
This is coming from a non whale with extremely good stats, better than most of the people (including whales) on the server; 2nd or third best in terms of stats (and I have excels of the majority of the player bases stats).
If you rely on the void, you are in for a rude awakening come duel time. Why? Simply because everyone else is also doing the void and using other means to improve their stats in addition to that.
Whales have an absurd advantage in the early and mid game stat wise. It's a total joke, we're talking 30/30/30/30 in all very easily and it isn't until several months into the server where proactive min-maxing f2p/patron + 1 $$ hero players finally catch up.
If is way more than just 30%
You get 30% more damage, while your HP is 30% less, and You also receive 30% more magic damage, and the attack speed of your opponent is 30% faster.
Just a simple unscientific math will be (70%) ^ 4 = 25% power than your opponent. If 25% seems too much, I think you will agree it is more than 50%, if you just consider HP, Damage, and attack speed.
I get the importance of stats but I think this is too much.
Somebody having 30% more hitpoints than you is not the same as you having 30% less hitpoints. It's ~23% less.
30% more damage + 30% more attack speed probably looks like this: Base damage * (1+ multipliers + 0.3) * (1 + AS multipliers + 0.3).
Using spiders as an example: With 30%/30% (I verified my math with in game numbers for the base formula) I'd gain 20.6% more raw damage, and with attack speed gain another 29.4% damage bringing the total to 50.1%.
If we do this math for the hitpoints of scorpions: You get 21% more actual hitpoints with a 30% bonus.
As you can see here, all of the modifiers but command are far more reasonable than they appear. Attack speed is a rare stat, so giving 30% to all is excessively good but that said, damage/hp modifiers may allow you to reach thresholds where stuns get applied to enemies, or not applied to your units.
