Still the roids produce too little output, can build enough offensive units to keep on landing without a single roid to hold.
On a single target round that is.
The XP needs to be turned in to value. Ie. every 5k u get is transfered to resources instead of score. Will help u to catch up the ones on lead and also the values will even out so you can xp back too. What good is score anyway, the ships and roids makes the battle.
XP is brilliant, best feature in the game, but how it is used right now needs a fix as mentioned above.
I suggest limiting military centers too, as other options are limited also.
AMP and DIST needs to become same level on resources and build time.
