I´ve just got idea, we all know that Cybran shield are recharged after upgrade and make them ED5 is extremely expensive and take very long time
so what if those shields got new toggle ability called let say "shield recharge", on as default
-- if ability is on, then shield will act like now
-- if ability is off, then shield after upgrade will not recharge and all so upgrading will be cheaper and need less time
-- so under fire you would have expensive rechargeable shield after upgrade, but if you just want get better protection for your base(not under fire) you would get cheaper upgrade with less time needed to upgrade
--how would it work if ability is off? ED1 has 4000HP, when you upgrade to ED2, ED2 stay on 4000HP and will slowly recharging to 7000HP by ED2 shield regen(130HP/s it has?? dont know)
sum ED1 shield cost/time + all upgrades cost/time = UEF T3 shield cost/time (just similar)
would be nice trade for nerf TML!(ED5 as T3 shield would be all so nice)
