I'm on the fence about this.
on one hand: I dont like the lazers, i understand what they are going for, but the counter play will always be wait for minions, or beef up to tank the damage.
On the hand: I want the towers to be more efficient to avoid tower diving with minions around.
Have additional mechanics to defensive towers:(not all of course, just some ideas)
- an AOE slow (turrent range) when enemy champions are detected (once every 4-5 secs)
- more than one tower shot (one for minions, and/or one for enemy champions when attacking allied champion)
- as less towers are on the map, the remaining towers get stronger in damage etc (small buff for escalation)
- proximity detection, as soon as an enemy champion is detected in behind the turret, turret fires of them, not minions (priority on lowest HP champ) <----my favourite( could use tuning)
- Turret aura's: Shares Armour or MR with champions while under Turret. (small area and allied minions affected)
- Damage dealt is true damage (lower starting damage, ramps up for escalation)
just some ideas, Turrets should be feared until ready to take on.
