1-DSHK is doctrinal.
That doesnt mean it should be immune to balance changes, or are you ok with 6 popcap pfussils?
2-It has many counters: LeIG, mortars, walkin stuka, smoke + anything.
Don't make another commander useless plz.
LeIG comes late, is expensive and isnt at all effective at stopping mg spam.
Walking stuka gimps any sort of light vehicle play, and is countered by a simple reposition.
That said, DSHKa doesn't necessarily need nerfs, the LeIG just needs to be rebalanced. IMO it should have a chance to hit or a lower arc when it has LOS perhaps with a lower range. It should really be like a mini Zis barrage.
