This is my opinion, and I would like to share to you:
1. Safari event?
It is called event, so that meant everyone has their RIGHT to access, also SAME chance to encounter an epic rare.
-> FAIR enough?
2. Economy?
Pricing depend on PLAYER at that moment - on trade, we don't force you to buy or sell anything.
For an example, regular MS went down from 2M - 1,7M - 1,5M - 1M - 500k - 300k - 280k - 250k - and 280k now, if you think it is unfair for those players who did buy a MS with 2M, will you buy a MS with 2M now?
I got a shiny Aerodactyl 3 years ago, It is the first one in Red server, extremely rare, and S.O offered me 20m for that, and now it is only around 2-3m on Silver trade channel. Is it fair for me and the player who make an offer? Ofcourse, because that was a reasonable price in the pass. You see? the price depend on player. Otherwise we also have "price check" from ALL channel. So there's not such thing like unfair for buyer/seller, except scammer.
FAIR enough?
3. Unfair for people who put so much efford in hunting?
You really think tier 8 in one week is something "extremely easily to get an epic 25+" ? No, 1 week doesn't makes sense. Yes I admit there will be some player with god luck can get an epic, but not most of us. That is just a few player, and you can't say that it is unfair for you who put so much efford in the game. We don't force you to put that much efford, you still can wait for the event, and enjoy with "low player", right?
4. Afterall
If you still think the event ruin the price, rare chance, etc... just think again. Without event, there is always somethings "change".
