Why is this rotation dispute so hard?

[falendar]

here's a quick easy way to solve it.
2hour engage timer
if you joint raid both guild are dropped to bottom of rotation for that kill.
no tiers
no strikes
easy and fair for all you rotation nuts.

The only reason to set up tiers/strike system is to strangle progression for the smaller guilds and make it very hard for new guilds to even break in.
