I have a lot of ip for some reason, and I've had an interest in karthus for a while. Is he worth buying? Or is he useless right now? Who is he good against and who is he not good against?
If he's not worth buying, could you mention some fun mid laners? Preferably mage casters and not ad assasins.
Man there is no good right now/bad right now, these things change all the time.
If you buy karthus you are stuck with mid lane. I you have no problem then sure buy him, but if you want my suggestion, since you mentioned if he is good right now I'll tell you buy a champion with more mobility, they are good right now. Consider leblank she costs the same and she is a mobility freak, also ahri can be very good. Victor is also becoming the meta, more and more people play victor mid and he is good.
If you want to go for immobile mages like karthus, Cassiopeia, xerath and malzahar are also fun to play, I find karthus to be boring.
