It probably will affect the recommended Refresh Treshold, which is currently defaulted to 4. This should most likely be 0, since there is no point in refreshing Tiger Power ahead of time since you don't loose any stacks.
There are other changes, Power Strikes in particular that will have an impact and an update will follow shortly after 5.1 is live.
