this is because of the new drop rates
they increased t2 and t3 units drop chances from lvls 3 and onwards
this means that attempting to 3star a unit is extremely risky
but something is bugged after they changed it since from lvls 1-4 im barely getting 2stars even while some dude always gets a 3 star
1 out of 8 people and he stays at first place until like 4th-5th stage just because of the 3star and if he doesn't fuck up a build he will most likely win
currently i think that the t3 units have a very high drop rate very early in the game and most builds can't function (ie every build that relies on a t5 unit > blademasters, nobles, knights, glacials, imperials
while builds that rely just as much on getting the units but don't have such high costs get to play and win a lot easier > assassins, sorcerers, gunslingers, rangers,shapeshifters, elementalists
more units need to be added and an algorithm that gives you increased champion drops for owned 2star units
like 5% increased chance to drop would be nice
because yesterday i was trying to build a darius literally nobody was building darius and i wasn't able to get a 2star darius until lvl 5...
