Win/lose strike.
while winning strike is completly fine and cool, sometimes it give a way to big lead for the winner. but lets ignore this for now.
the fix should be in the other side of the spectrom the lose strike.
we just need to buff it, and not by gold.
just make lose strike persist, even after a single win. maybe, switch from immediately switching from -4 to +1 to, going for "promo" and if the player wins at least 1 game in the next 2. he would go into +2/+1 win streak (if it was in a row).
anyway, that would make a very huge shift, one. winning a single match would not break a lose streak and would be much easier to control, overall. also it would mean that there is much more room for comeback.
As for winstrike it should never get the same "buff" because winning should be prioritized, its already giving you a +1 gold lead each round you won. while losing just suck, and getting 5 loses in a row is not fun, but at least with this change it would be possible to play around with it.
maybe like Get to -8 then Win one, lose 2. and still be on -8.
