For the entire duration time an "Event" is running, the ratings should NOT be re-set upon re-entry. Here is why ......
Too many players that are WS caliber players in RS & 12-0 caliber players in BR that finally lost their 2nd game after winning 6 plus games are being matched up with players that are only lower tiered caliber in RS & that at best may get to 4 to 5 wins per run in BR. The rating being re-set on each re-entry allows this & as well the rating match up slider can NOT be held to the far left like in RS.
Having the ratings NOT be re-set per re-entry will give everyone a more balanced match up to others at or close to their own playing level. It should be just how it is for the duration of the current RS in progress. As you win you go up & as you lose you go down. However being re-set on every re-entry is just outright unfair and basicly a cheat for those well advanced caliber players because the are getting easy guaranteed wins over players that are not at their level of play. Any player that wins 6 to 8 or even 10 games in their previous entry should be facing the same type of caliber players upon re-entry. A player that won 0, 1 or 2 games in their last entry should be matched with other players having those same results.
This is why ratings should NOT be re-set upon re-entry.
