Honestly the 50% damage boost like WB would straight up as a general ability, not just in his Hype Mode only.
I'd make a dragon ball z joke and probably say Beowulf is truly Yamcha now in this case, but I mean, to be quite honest I also feel like they should give him an ability that at least isn't stuck IN hype mode unless it's something like how WW has Last Stand since that's his gimmick.
You
want something to be of use to want to use hype mode, not try to throw yourself in using it just to get a bonus you could have gotten as a passive ability and I feel that's the real "problem" so to speak.
35% crit rate is totally awesome, crit damage of 75% extra is great! But, not exactly for when you're using hype mode because most of the time Hype Mode is geared to adding damage to Beo's BB's or grabs. The crits don't work on those so, you're stuck with you're basic combo -> Launcher and so on.
If it were like, I don't know, besides Peacock's ability I spitballed, you could say like, he has the crits passively and then in hype mode gets an regen for 10 seconds and when defeating an opponent he gets armor (or the original
bb's getting filled by 50% by using one to beat an opponent.
Keeping him restricted towards surviving outside his main gimmick / playstyle isn't really as great as it's supposedly made out to be when most of those don't actually crit with his ability.
