Covert ops isnt what it used to be to prevent roid loss from the casual Basic Agent Training /
Exploding Fist which forces early cov op immunity and makes cov ops stale before its time.
what I''m proposing is a change in the cov op tech tree....
Basic Agent Training (starting technology)
Research Transferral
and make exploding fist the 4th tech in the covop tree
IMO this would make cov ops more exciting and less likely to stale cov ops via everyone going immune.
