Oi, lolix, i would like to ask if you even read my post on the last page.
I will ask you the simple question:
We have two silver rogues, Cecily and Harissa. Are you going to get them both to 50CC50 and use them? I can understand EVENTUALLY max affing them for scenes, but are you going to use them? Feed every extra copy to them to make them "great" units?
If the answer is yes, then i guess i am out of this case.
If the answer is no, then you have to know that MANY event units will be just as useless as that Harissa/Cecily you just skipped raising fully. Will you still work on getting all those "useless" units to max skill and CR by mashing an event?
Because if not, then these events are the perfect ones to only 3star and get a copy of the unit from. The rest of those events you can do dailies at your own leisure and fill up your stock of items again. We will get MANY of those "useless unit" events in the future and we will most likely even be told this or be able to deem this ourselves ahead of time.
So in this case, we will not need breaks because all the units we get and won't use will overwhelm us and we can spend all those events just getting more rubies from phalanx 2.
