A simple QoL change - Drops in boss

It's sometimes hard to distribute every stuffs in 180 sec (which is perishing time of drops) in fair.

We gets kicked after 300sec of end of boss anyway. I hope to suggest drops remain till the end of that 300sec (just like x-mas tree deco map).

that additional +120sec will help us a lot for deciding who to pick what, and I can't find any side-effect of this except very rare case, like, bishes ress cd remains like 3min when boss dies, and possible to ress buyer and letting him/her pick drops with it.

I believe this will prevent dramas a lot in bossing, and be helpful for community also. since bossing is for communication and socialization, wish it be fun till the end.
