Archangel/Tear is Bad Design
This is a mage main calling the item unbalanced.
It promotes unhealthy gameplay. At 3200 as a first item, its just too damn powerful and way unhealthier than the old Morello. You end up with 20% CDR, a good chunk of AP, and an extra Barrier to boot. However, the worst part is the Tear.
With just a single Tear, you get to wave clear with nearly INFINITE mana.
I played Viktor, Ziggs, Lux... its the SAME strategy. As soon as you get a SINGLE tear
BYE BYE STRATEGY
You get to sit mid and just wave clear/perma push endlessly at absolutely NO COSTS. I can only imagine this is even more OP on someone like Annivia or Xerath.
There is absolutely NO COUNTERPLAY besides the other Mid also building a Tear and then having both of you mindlessly hitting waves and looking for other places on the map to Roam.
ITS BORING, STUPID, and UNHEALTHY.
I play Mid so we can have exciting 1 vs 1s... not so that we pick a "blue" mage (or else get out-shoved) and then wait for the 1-2 item spike. The only counterplay to this Blue play style is to defeat the Blue player's team (or go Blue yourself and hope your team does better). That's not good active design/playstyle.
How is someone like Zed, Fizz, Kat etc supposed to COMPETE against all of this Blue stuff being spammed? Its literal FREE wave clear and on champs like Ziggs, Xerath, Vik etc there's just no counter. Without minions, you can't take Mid nor mount a sustained assault.
I think Tear needs to go... otherwise its going to be a Mid Lane Tear meta. And its boring.

and
can already absolutely destroy him
and
can beat him if they keep kiting etc
and
was that with the former, you at least HAD to manage your mana. With the new Tear building into such a smooth first item... you can now get it, come back, and then auto farm/perma push completely.
