Yes! There is no need for them after their event concludes. The extra two weeks is a great idea, especially since so many are unable to breed the dragon during the event (which is a whole other can of worms...). But, after that two weeks, they should be GONE. I'd like to see them removed if only because I am sick to death of seeing them, lol!
There is something I have been wondering: are they actually super commons? Post-event, I get way more of the event commons than the older commons: 3 Enamoured to every 1 Winter, even though the same combos can produce both. Don't even get me started on Neo Flippin' Bubble. For every 5 NBs, I only get 1 Coral. They're identical, rarity and type-wise, but one consistently turns up much more frequently than the other. It's been happening at such a lopsided ratio, so consistently, and over such a period of time, that new and the old commons appear to be weighted differently within the common dragon pool. This is only speculation based on lots of observation over the past year.
(The NB:Coral numbers are probably a better representation because I have been breeding for black hybrids *a lot* over the past year. I don't do white combos anywhere near as often. This matters because if NB and Coral are weighted equally, the gap should be getting smaller, not larger, with more breeding results/data)
Ok, bear with me. I have theories, as usual. Here's what I have been thinking:
At first, when the first new commons came out , I was like eh, no big deal. A common is a common. There is always a 65% chance (or whatever- I forget the exact breakdown of rarity odds, but 65% is in the ballpark) of getting a common outcome. More unique dragons added to the common pool doesn't increase the chances of breeding a common. The chances of getting a common as opposed to getting a rare, super rare, or ultra rare, will still be 65%(ish). More dragons added to the common pool just means the (frequent) common outcomes will have more variety, dragon-wise. That was my thinking when they first started coming out...
But, since then, I've noticed what appears to be an increased chance of getting a new event common instead of an old common. In general, the 65%(ish) chance still seems to be intact. Commons are, after all, common. But when it comes time for the algorithm to assign which particular common dragon you are getting, to draw one from the common pool, it seems the new ones are weighted more heavily than the old ones.
Idk. Something seems different about their drop rate within that 65%(ish). As for a possible reason why, they only thing I can think of is Bingo. The new commons started coming out (roughly) around the same time Bingo was introduced. Bingo awards high points for breeding tasks. Maybe weighting the new commons more heavily within their own pool is a way to hamstring that? Hoping people will spend gold to speed breed past 5 NBs to finally get that high point Coral task completed? Idk, just speculating and trying to make sense of it.
Whatever it is, they gotta go. If I see one more Enamoured or Evil Bubble I'm going to start breaking stuff.
Edits: brain farted with Enamoured/Love/Winter. I blame Wonder breeding stress.
Changed Love to Winter at the top and changed Bingo example in last paragraph.
Enamoured is sooo on my s-list right now.
