Telegraphed spell has nothing to do with ''oh this should cost less''. I took Sona as an example of how unfair early game mana cost was. I could have taken Nami's W if you wanted, or Blitzcrank's grab. Want a top ''telegraph'' champion? Jayce would be a good example, all of this spells cost about 50-70 mana in early game and he can easily run out of mana.
Morgan's arguments don't even stand at all.
Q dmg range from 12-120 based on charge time. him saying '' Inversely he has to stun himself for at least 1 whole second - upto 2 - in order to get any cc or damage out of it'' is false.
No matter how long he charges the Q, if it hits a target, you get a guaranteed 50% slow
W's shield is scaling on MAX HEALTH %. That is not a small shield. Sure it looks small on him because of his massive health during late game. Either way, you don't max his W first.
E's initial target range is 725, if it hits a minions, it goes forward up by 775 range for a total of 1500 range. EVEN if this spell a telegraph spell as you would say, IT'S 1500 POTENTIAL RANGE for 35 mana at level 1 that slows for 2.5 seconds, reduces armor by 20% (hidden effect for adc?) does an increased 30% magic dmg to all subsequent ennemies hit by E. Even Xerath's Q range or Jayce's blast aren't that far. Combined with Arcane comet and scorch, you get a 150 dmg spell for 35 mana on a 12 second cooldown
If all you have to do if to Avoid his spells to counter him, heck, that would be the same against a Xerath mid, and life would be easy.
But you know what, you can Keep using Morgan's argument against me even if I just proved them wrong. This conversation is over.
