No. If you want to play PaladinGaren then start with the followings:
Sunfire cape should be your only tank item early on. Like the only one. Gives moar dmg while spinning and a hefty hp and armor amount so you won't get one shotted and survive until ur spin+ult animation goes off.
Boots: swiftness. You are not tank and you still have your W for inbuilt cc reduction. Also it's cheaper than merc boots. Fuck merc boots. Real retri palas don't go merc boots. Get swiftness and run like a nigga towards your victims.
After theese 2 you get the "core" of paladin that is IE and STATIK. Ye, statik. Thing is your Q procs the statik, gives more MS and has less attack speed (which is kind of a wasted stat cuz you only need crit and the ms so phantom is a big nono) it also hilarious when your Q crit for 800+dmg AND the +200 magic hue.
After you get theese u can worry about ARP/CDR. Last whisper, cleaver will be your best friends. If you have something unavoidable then mix in Banshee whenever you feel like it.
