There is a few work around for this if not addressed.
1st, you could bring a friend to interrupt for you, not ideal and also means that you cannot solo, but still it's an option.
2nd is actually not dissimilar to using a trick that we needed to use for our old friend King Krush (back in the day) and that is, bring a pet friend.
To tame Krush early on in wrath blood lust/hero was a must to get our tame in before the next fear. People were using drums and haste potions and haste gear and haste trinket procs.. and, well anything to get us over the line. The biggest problem most found was getting lust/hero. By this expansion however, we had our own in ancient hysteria from corehounds. People hunting for Krush were taming a trash core hound for just this tame.
There were macros that involved, chugging down pots, using trinkets, casting ancient hysteria, abandoning your trash hound and then casting tame beast. It was crazy, exciting and nerve wracking days, but back to the current problem.
This time however, all we need is another pet to help us out, a Gorrilla with their family ability Pummel.
Instant 30 sec cooldown
Pummel the target, interrupting spellcasting and preventing any spell in that school from being cast for 2 sec.
and there is your interrupt as BM.
I would suggest you turn growl off and limit the use of KC to make sure you’re the one with the threat at all times. One your engage have your pet on passive for a little until you get an aggro lead and then send it in to smack away at it and keep it in rage for Pummel when needed. Once you get Hutia down in health enough to tame, interrupt it’s next heal once more, stand behind and frost trap and then use ye'old faithful abandon pet macro, /deterrence, /tame beast.
Hey presto, Hutia on your BM.
And in before people complain that that’s too much work/too hard to tame it, it's a hell of a lot less than Krush...
(Which I don’t remember hunters QQ'ing to blizzard that "it's too hard for me! Why do you hate hunters!!!")
Hutia, had a 10 minute spawn timer
Krush, good luck finding him even once, than alone and if you got one attempt before he was ganked by somone else.
Hutia, screw up and abandon your gorilla and need to try again, not to worry there are gorillas just around the corner in the same zone.
Krush, was there even a core hound anywhere in Northrend?
Hutia, bring a full stable of 5 Gorillas? Not that hard now with 50 pets slot now.
Krush, Hmm 5 pets, which pet will I have to lose to have just one gorilla!
Hutia, pummel, 30 second cooldown.
Krush, Hysteria, 10 MINUTE! debuff cooldown.
And in before people complain that we should not even have to deal with this, they broke it by taking away SS, it's not our fault!!! I know! It's freaking annoying, I'm with you on this one, the only class without a baseline interrupt, it’s pretty much a really really bad joke. But.... if you really want Hutai next patch and they don’t give us an interrupt...technically it's still doable
