2x mother ships with lvl3 shield restore 2x guardians no need for more, you wont deplete the shields EVER it needs to stack or it needs to get a complete overhaul.
and no it does not happen very fast, atleast not multiplaying focus fire and *only* 33% + a mothership
it makes it a no choices have to be made, if it staks with diminishing you have to choose to use your fleet supply to dps or for survivabillity
the entire point of it is to make focus fire less viable, unstacking you just focus down the guardians and take it from there
stacking you would be better off having your ship take on their types counters to get the shield's down as fast as possible
making the entire fleet loose it's shield at aboutthe same time
If focus fire is bad, then stacking is a must
If focus fire is good, then stacking is bad
IMO focus fire is BAD, but that ofc is just opinion
dang just updated to 1.12 i geuss that means vasari/tec from now on then if it no longer stacks
QQ and here i thought they where taking it the *right* way and moving away from focus(if focus fire will kill anything in 5sec then the strongest econ wins, /wave at TEC)
btw not stacking make gurdians= clio's
but horris are way better than dominas (3sec cd heal vs 20src channeled)
