The issue i see with serina

After playing a few games of PvP in 3v3 team war I have come to the conclusion that it is extremely difficult to counter a team that has her with either a rush or a turtle due to two things the first is her glaciers that just stop me when I’m trying to push and when I push through to her base she has the option of having 5 of them and if I turtle then I have to deal with her over powering me and taking the power nodes allowing her to run rough shot over me due to frozen nodes imo she kills early to mid game for most leaders
