I agree the arty needs some nerfs, either range, AOE damage, accuracy, rate of fire, etc. even if it was only more expensive it would still be so effective, u don't need many to destroy an attacking army before they can get in range.. so if it kept its strength than it should become A LOT more expensive, like 5-6 times more..
I agree the caregiver needs a buff, units die so quickly, that the medic is actually A LOT more effective, it doesn't help if u are repairing the entire army for so little damage that they are dying anyway, compared to the medic that can keep all the essential units alive. and for considerably lower cost/log
I like that the sky ender can attack radar contacts and has greater range, but also agree it needs more damage
The drone swarm too expensive? Sorry this is where I disagree, for one u need to consider the majority of players (who are not the top ranked) when I first started playing the drone swarm killed me almost every time. if u don't have AA as PHC u are dead. which means an Apollo. an Apollo is overly expensive just to counter a POSSIBLE drone swarm, and then where will the drone swarm lay? also the drone swarm lasts for >1 min, so If u DO NOT kill it with AA, it can easily destroy a lot of ur base. so no AA, and the enemy uses drone swarm = crippled. compared to the plasma storm? that lasts 15 sec, is dodgeable (with good micro that I could even do when I started playing) if anything I think the drone swarm should become a more consistent power, currently it dies too easily to AA, and does too much damage if u don't have AA.
I like the tech wall on the recharger, but then I think the recharger needs a buff (the tech wall is to prevent early turtling being too strong) whereas the tech wall + buff means the recharger has a use in later games as well..
I only use groups now when I want bonuses from the dread, or to stop people from sniping HVTs in my army.. like Apollos.. or my cruisers amongst my SS spam mongol horde.. otherwise units operate more effectively outside of any army..
I find the retributor less effective than the overmind, since atleast the overmind has that shield buff thing, even if it doesn't do damage...
