Just a tiny request for Slugger class

I read many writings about promotional classes and some says the demanded changes can’t be done for these classes because these are licenced and it takes too many procedures etc. If thats the case, I sit and cry =) BUT a minor change can be done ! Please erase reloading issue while slugger’s ultimate is active … a tiny request but this change makes this class more effective. Also please make its ultimate works on Brumak too. =)
Thank you

What I want for this class is that it gets immune to its own frags. It’s ridiculous how easily you can kill yourself with them if you don’t put half the map between yourself and the explosion. It’s also not going to break anything currently because no enemies throw any frag grenades in PvE.
