Once you fight Hate/love more you'll soon realise he does way more damage to you then any GK HA, Personally I'm ok with HXs but they do have a kinda unfair advantage imo. Love/hate for example takes two light crossbows and I think two sets of steel bolts and no melee weapon. He generally rides the fairy horse (Arabain poledancer for those who don't know) and honestly Id rather go on EU1 and fight all the ranged on there then him, because even if he misses and you somehow get close and he doesn't dodge he just pulls out his second crossbow and shoots you in the face.
He does really good damage and is near impossible to catch as well as hard to shoot at he is nearly always the last alive (no problems with that his a good player) however iv seen him take down 4+ guys before he goes down as the last standing and Iv never seen a HA do that.
I think you should still only be allowed to use the hunting/light crossbow but perhaps slightly reduce the damage they do and increase the reload speed slighty? I doubt crossbows that were used on horse back were strong enough to penetrate even half decent armor. Apart from the surprising damage they do I'm fine with them you don't see to many you see quite a few (Seriously why is there an increase in HAs and HXs? I thought everyone hated them and they are expensive to upkeep?!) their annoying just like HA but Id say HXs are fine just tweak the damage a tiny tiny bit and the reload speed.
