Call-in infantry isn't a problem, as most stock infantry can be produced early on anyways.
It is a problem. The unlock timing is inconsistent with your teching. If you end up waiting for a call-in to be unlcoked at a certain time you might end up floating a lot, forcing you to buy something you didnt plan on. Its unpredictable in fact. CP points is complete BS - the most retarded resource that inconsistently increases with random actions your troops carry out.
We locked EZ8 and su76/85 into tiers, why can't we do that with the rest. Relic nerfed so many call-in units' stats instead integrating them properly into the game.
Also, why the hell am I forced to pick a doctrine to build a stock unit (King Tiger)? #consistencyplease
