In my opinion, I think removing inspiring presence is a handicap for barbs.
If a DH user has good impale aim, and the barb has no inspiring presence, impale crits vs. the barb become very unforgiving, imagine 30k impale crits. You need 12-15seconds to regen just one crit? AND you have to chase a legacy nats user while being forced to take more impale crits?
The real "problem" with this matchup is not gear or balance in my opinion. I think Barb vs DH is pretty balanced. The problem is the SKILL level required to play.
It is extremely easy for a Barb to just sprint in non-linear patterns and try to cut off the DH with Leap/Charge. It is SO much harder for the DH to kite, manage discipline, react fast to leaps/charges, have unpredictable movement, need to have godly impale AIM (you never shoot at barbs, you shoot where they WILL be), etc.
I think this is just something that the players have to accept and overcome. It's very hard and needs skill, I know (and this is the most frustrating fact about DH vs Barb, that you have to outskill to be on even grounds). But if you interfere with this by giving barbs a handicap to accommodate DHs that have a hard time, then the "good" DHs will not lose to barbs
