In my opinion grayhound should be in t0 after u unlock full oficer. Because its really hard to balance cp timing espiecialy bettwen 1vs1 mode and 4vs4.
That would make it come way earlier in 1v1s than it currently does.
Timings is always an issue between modes. But it's better to have it underpowered in one (too late in team games) than have it overpowered in the other (would come way too soon in 1v1s).
The only way of resolving this would be to manually adjust XP values so the CP gain for all modes becomes relatively equal. But that would take a very big amount of work.
