Hacking 5th Ed.

A couple of rule changes/notes for my 5th ed game.
Initiative
With 6 or 7 players plus the DM, tracking individual initiatives each round is going to be a real pain in the ass. Instead, each round the DM will roll for the opponent with the highest Initiative only, while each of the player's will roll for their character. The highest roll goes first, and then we will just go clockwise around the table.
Monster StatBlocks
As written, the monster block stats in 5 are fine for a write-up, but to bulky for in-game notes. If I'm running more than one kind of monster I don't want to have to flip back and forth in the MM for every different attack. So I've compressed it down to a simpler block of stats, and combined it with my idea of a Combat Chart (basically, roll to determine what attack the monster will use each round instead of 'round counting' which is absolute least favorite part of rpging. DMs can choose a specific attack instead of rolling.).

XP is divided equally between all characters who participated in the combat, with any remainder going to the PC who delivered the killing blow.
