ok...finaly after a month of waiting i can write here...
so about angels...yes, they are not worth that cost...its fact
solutions? hm...mb double strangh or numbers (or both) (mb cuting cost but i think costs are balanced and not be changed for a long time or never)
but if we will look at all citadel upgrades, we will see what many of them are some sort useless...like 2nd+ upgrades for hp/damage for grunts and hp/damage for buildings and bonus exp and reduse death cooldawn...all this after first one are simply worthless
even if we look on this from 5v5 game it is still useless...its not comulate with each other but replaces each other...
catapults on building only worth if u play with 4-5+ fortresses...
finger of god...i dont know exectly what this s**t is doing but i think there are must be a nuk one weapon what can make realy big damage at final stages of the game (not a 500 damage...what is 500 damage whan u have 7k hp and reduce 50% of damage and crazy hpreg?...so i can say what it is worthless too)
so...what we must to buy at citadel on nowdays?:
-1st +hp/hpreg for buildings (must be for prevent early defence crush)
-1st +damage for towers (not realy must be, but not expensive and give some bonus)
1/2/3 gold income (if u play 3+ vs 3+ this upgrades have priority i think u understand what with them u can easly get access for 13-16k artifacts and have all what u need)
-1st +damage for grunts (1200 for +20%...can be usefull...imho...dont know exectly) (but sumary +65% for 12K+ gold...dont know...for me is too expansive)
-1st +hp for grunts (i think its not hard to buy)
-1st +exp (must buy fast
) (3 others - for what? when we have 6 WL we simply going to good item and catapults...if we are loosing, we simply havent money at all...)
-1st -dc (not sure...mb can be ignored at all)
-prists (if u get 3rd WL u must buy it
-angels can be ignored for a long time - catapultozaurs (buy if u can) -giants (u must have gold for them!!!
)
-trebuchet and FoG can be ignored
so we can see what 50%+ of citadel upgrades are worthless and must be rebalanced...
