Ok.
First of all he now has 3 Q charges all levels, so unlike before, when your enemy was good at destroying the turrets you can place new ones faster. Before you could only place 1. By doing that and nerfing the Base Damage of the AAs I tried out doing the W Max first and it was working quite well. You need to hit your Skillshots with Heimer. A level 3-4 W can chunk your enemy's health to half because TLD.
If your enemy is melee and wants to destroy a turret, thanks to your passive and Q changes you can place 2 turrets behind him and throw your E, which has now a bigger radius. You only need to hit the slow, so 2-3 turrest can laser beam his ass and chunk his health super good.
When you're good at landing your W/your enemies are bad at dodging then I don't buy Morellos. But what I absolutely love now is that it is possible to 1v2 more often now, especially when landing your skills, because it is really rewarding now.
One thing I didnt like about the change (which should probably stay that way in order to make him really annoying) is that they made the enemy minions attack you, when your turrets attacked the enemy (You didnt AA the enemy). That Minion Damage level 1-2 is pretty big.
But all in all, I fucking love the changes
