VelKoz/Xerath are so hard to deal with bot lane
Out of all the champions that are played as supports, you know Pyke, Zyra, Brand, Lux, this 2 champions are just unplayable, they stay out of engage supports reach and slowly cheap you down spamming abilities on cooldown. Enchanters don't stand a chance against them either, they can't repel this much damage.
Most of them are also mains of those champions, so they play very well and abuse their poke to make the life of normal bot duos miserable.
There is a reason ADCs don't work well in solo lanes, so why mages should work well as supports or even in the place of ADCs?

counter the entire Xerath kit. Just get used ot hitboxes. The Q's is a bit hard to tell if you are not used ot it because the beam visuals are not on ground level and thus it might seem different than its hitbox.
is insane
