they cannot give us the old music, sorry man, if they wanted to continue using it in game it would cost them money, that was the reason for change in music - the finance
and about a legendary gate - i dislike it. i think it would bring no fun to the game only boredoom and annoyance while everybody would put it in their defense team and not offense… do you really need to make your pvp even slower? 
but i do like the idea of reworking pvp tier representatives. somewhere around tier1 could be things like mythic war, and the zombie can stay on the bottom xd
