I dont say no limit at no limit , i say no limit at high limits, like when it turns 200/ 400 or higher , it gets nasty .
.
6542A
6532A
Things like that ...
Or even beter
3 people from which one has
5432A
the other one 6432A
And the other 7432A
At higher limits it gets nasty, but noo ofcourse not all in with only 3 cards in your hand ofcourse not that would destroy the game like you said, and yes pot limit is nasty aswell .
