the shrine sounds kinda lame,I mean Zyras seeds to exactly that and can be used for more(teemos shrooms are an even more extreme example).
And generally the other abilities are simply not very special.
has already the same passive(in fact its even stronger)
The W sounds a bit like
s heal just without the healing for minions.
the ult sounds like a more powerful version of
s Q(or
s W if its a targeted skill)
I think the Q would be the only really unique ability,but only because we currently don't have a skillshot with silence.
Overall it is best if every new champ has some kind of completely new mechanic,it hasn't to be groundbreaking but should still feel different from everything else.
I mean
can go 4 seconds back in time,
can cast a mass zonyas and create portals,
can dig tunnels and burrow into the ground,
can jump with every autoattack and bond/throw one of her teammates,
can summon soldiers which he can also command,etc.
Of course not every ability needs to be a revolution,but it would be still cool if the individual abilities have something that sets them apart from the abilities of other champs.
I mean look at Ekkos Q for example,from the way its used it is basically similar to sivirs Q,but the fact that it returns at a delayed speed and that it expands on contact with an enemy make it at least more unique.
