Only thing which is broken about partisans: AT partisans spawning in buildings,shooting a shrek hoping out and AT nade the vehicle. AT partisans should have full CD on AT nade after callin in. It denies light vehicle play on many maps completly.
No late game heavy vehicles. No offmap artillery. 4-men squads that get gibbed a lot. Usually you pick the doctrine if the enemy, for example, overextends a little his puma or luchs and then you want the shock value of finishing it quickly. I'd say it's totally fair.
