Ultimatum Minion Spawn Lag Spike

I run an Infernalist build with constant suicide bomber that go boom and respawn. On later rounds of Ultimatum, the minion respawn would cause big lag spike. Thus making it a 4-5 seconds lag spike interval as it is the time it takes for my minion to respawn. This did not occur when I had lower amount of minions. I have not done any testing yet, but when I increased my amount of skeletal warriors to 26 it was giving me the lag spike when they respawn. IT is pretty consistent too :) the minion spawn, lag, lag goes away, minion dies, 5 second wait til minion respawn, rinse and repeat.

Here's the footage I've captured:





EDIT:

The modifier that gives buff expires 3 time faster and debuff 3 times slower also syngerizes with minion respawn time which I think is pretty funny :D


It only seems to be in Ultimatum.. only. I primarily run Ultimatum cuz its fun :D, but I've tried a juiced up t15 map and it runs normally no lag spike. I have not tried Trials of Sigma yet so maybe I'll to test the build there as well.
