SUPPORT / HEAL / RESCUE BEAM NO AIM MCGINNIS

BUY ONE OF THESE INSTEAD OF MAGIC CARPET WHEN IT'S SUGGESTED
Pick between Divine Barrier/Slowing Hex depending on how much you trust/hate your teammates/enemies
Don't forget, RADIUS is only half of the DIAMETER
Double any size increase of your healing for its true value
Remember that Medicinal Specter doesn't stack with itself
Oh, and DON'T BUY MAGIC CARPET
Seriously

Hooray, somebody to blame when I lose! Buy these in order.

It's okay
If you lose, it'll be their fault for not swapping
Buy these in order.

Find new places to be an obnoxious tumor
Buy (mostly) in order.

You're kidding me
What is your team even doing? I don't know, buy these, I guess.

Always be sure to keep two lanes pushed and steal farms
You're backline, but just because you're fat doesn't mean you shouldn't be fast
Get yourself set up, and lay into that ult from a cozy range while using Heavy Melee Cancel to get out
Always place your sentries apart and in weird spots, you use them for the debuffs, not the damage, since THEY WON'T STOP NERFING THAT SECOND PART
If you see a teamfight, chuck your heal in the middle of it all and plop your turrets around while waiting to either pop an active item or your ult
You capitalize on enemies overextending and punish them hard for going in
Your teammates will immediately recognize your zone as a safe area, so make sure the place is always up and running
Don't be scared to solo objectives, but only make yourself known when you've got all your abilities ready to go
Otherwise, drop your sentries in camps to quickly farm them
Identify when two turrets is enough to clear a camp and just drop them there to steal it from your enemies
You are a viable candidate for claiming level 3 camps with your ultimate, so don't shy away from that.

What, my build isn't good enough for you? You think you know better?
