As in, not even in late stages of tournaments?
Nope!
And this leads to, if anything, the reason ante's were invented (OK, at least a reason they are useful): Games lasting too long.
Late stage O8 tourneys these days are nit fests. It is very common for the end stage players to do nothing till the bubble bursts. They will sit out often, but more often they will eat the clock using a delay to make sure the next blinds take as long as possible to get back to them.
This primarily only happens in O8, most Omaha tourneys have ante's in the structure.
I must be missing some key info as to why O8 tourneys developed this way.
Ante's are not a factor in cash games. We really only see them in the STUD variants. Mostly anyway. Most all
poker games originally had ante's, but then someone invented the blinds, probably because it was easier to keep track of and the blind structure was tweaked to what it is today. Recently I had seen that Stars had even begun to migrate blinds into the Stud tables. Weird at first, I got used to that pretty fast.
But in Tourneys, the ante's speed the game up.
Online, a 75 player tourney shouldn't take over 4 hours to finish. O8 tournies usually do. If there were ante's that started right after any re-buys and add-ons, that time would drop to somewhere around 3 hours.
I have played O8 tourney's live, and they wouldn't take that long! But they had ante's, and were a variant (5 card O8), intended to move along rather quickly
