League experience

Ok I started a witch/lich about a week into the league. I first was gonna do a cold skill minion hybrid with ice nove to freeze adds close use minions to kill frozen adds. It was ok until act 3 then I stop freezing things in 1 to 2 hits and it takes me 4 to 5 to freeze. Got higher so added a cast on minion death with comet to try and help support damage. Comets are to slow and way to many minions had to die with 60 % increased energy gain. So I decided to fully ascend and then there are no good options for lich in summoner terms. Decided to kill kulemak and try abyssal lich. Wich in my opinion is the worst summoner ascendancy in the game. Long story short I kept trying all kinds of different skill combos, gear, gems, everything and all I succeed in was wasting all my money and currency and left with a none functioning character. I'm not a blaster and dont mind grinding a bit early game for gear and currency but its just none existent this league.
