Thank you for milestone and advancing further suggestions

Bad

Milestone is a great feature rewarding and encouraging roster development. Its great for players interest and game also. Nothing to object there.
Now I think its time to advancing further, providing a mode for to gaining a bit more putting some extra effort, aimed for advanced players.
It should be a challenge similar to those green nodes, with pretty hard fresh foes ala simulator pve.
With newest characters entry scl10 has become a bit outclassed and a lot of players found pretty easy to beat it clean and fast.
I think now more than ever this challenge mode could be pretty exciting and enticing for those players and for wannabe advanced ones.
Offering some of the most precious rewards, support tokens and 5* favourite shards, as well as the now revalued iso, this nightmare mode( previously specified) could reflect some of the next treats:
-Updated foes to the last releases
-Modified increased damage of the enemy
-Penalizing reseting battle with extra team damage
-A loaned character in some nodes being of relative help but not maxed
-Less possible clears to beat it
-Full progression rewards when full cleared nodes
-Optional extra ranking rewards
-Modified inmune to stun to a bot or a single member of the enemy team.
That were my 2 cents. Looking really forward to puzzle ops.
