Its a filter...
If you remove the filter you will have people bitching about t6....how hard it is......then you "FIX" that and then T7 is so unfair....
it is not an accident...
This is an extremely valid counter argument.
One of the more common issues in t5 is not being able to repop without spending a ton of plat. I empathize with that, but its pretty pointless to even address that when you truly can't do anything of value in t6 without either the FWP or joining a guild that has a couple. So like Balidet pointed out, fixing the cost/ability to repop in t5 would just shoe people into the complete brick wall that is t6.
Maybe look into bumping the t5 rares slightly?
What i would like to see is the Kill-All mobs/ bracer mobs removed from the Lotto Jackpot boss. Nothing is worse than clearing the zone entirely and seeing Corallium or Alkare as the lotto prize. Nothing... NOTHING. lol
And I really can't overstate how getting 5 random bosses a game day out of the mini was the perfect solution. Sadly, its a royal pain conceptually to stop exploitation and dev time better spent elsewhere, etc.
But that mini took 10-15 min tops, helped with progression in the hard to progress zone. Remember, the t7 mini does ZERO to help t7 progression. The Dranik does ZERO to help t1-t4 progression. The T5 mini was *huge* in helping t5 progression. Scoring a Bone Rot and a Aquamarine on a tuesday was a *great* tuesday. Scoring an extra White literally saved you two hours of corals as a youngling. It's the roughest thing for Akk and Co. to 'fix' (the t5 mini), but it has by far the greatest reward... It's the best solution to t5 help for the middle class, and I think everyone can agree on that.
