Unnecessary Changes in recent patches?

So we all know Zac, Rammus, and Heimer got a bit of reworks/tweeks.

First off I feel like Zac's rework wasn't really needed, but I still thought the concept was pretty nice. I just don't like his new Q, I feel if theres only one target in sight, it could do a bit more than just a slow and bonus damage on the next hit. Maybe a small pull? Or a harder slow if he attacks the same target twice?

For Rammus, I like the new W and R. I feel they're both fair and well done. As for the new Q, I don't like that it is a shorter duration, even if just a little bit. And not quite sure why they changed the passive, but I guess it fits in building a abyssal scepter more of a reason.

Now for Heimer, I'm not quite sure if they removed his old healing passive, which I thought was great. It fit into his theme, him healing his turrets and such. But the new passive is also great, lets him kit around his turrets a bit more. For his Q I really hate that they removed the turrets priority to target nearest enemy champs, or those attacking the turret, that really just dents the turrets use in my opinion. Also the range for the turret to be active is super small! I'll still be in sight of the turret and they're already getting ready to take a nap!? And the beam charge rate is super slow and long! I get they want abilities to make them do it, but from 16 to 90? What the heck is riot thinking lmao, thats like waiting for two ults to go off cooldown, maybe 46-60 seconds, thats atleast being fair... As for the other abilities, I got no problem with that. I think overall these changes are good, just need more thought.

Anyways, want to know what anyone out there thinks, correct me if Im wrong on some things. Did this off the top of my head, thanks!

Edit: When is Malphite getting his fair share in the mid-season tank update, our rock buddy has been waiting.
