Depend on cooldown but I'm reacting more about the "solution" proposed, -Yeah just back off out of Lefh range.
Should say the same thing next time someone complain about elefant or jackson range, just back off out of range. Why have we nerfed ISU range again last patch? you just need to back off out of range...
You are comparing apples and oranges here.
All the units you mentioned need constant frontline duty to be effective. Rocket artillery has literally nothing else to do than wait while on cooldown. There is no disadvantage to driving it back to the base after the barrage. It is literally the thing to do to keep your unit safe, regardless of CB or not. There can be problems on smaller maps, but the overall point stays untouched.
Mortars are slightly different since there is good reason to keep them near the front. But as I said, with those units this weird behaviour does rarely make a difference
I agree though: If possible, it should be fixed. But if it is too much work or breaks other stuff, it is not worth the time. If an issue needs years to get noticed (to emphasize:
noticed. We did not spent 8 years trying to look for a fix, we spent 8 years until someone finally realized that something is off. And the LeFH has been viable in team gamse for ages.)
