I was digging through my basement for my old chaos models from 4th ed since I am trying to get back into 40k, and found 2 vindicator tanks. I was wondering if vindicators are viable in pairs or if I should only field one at a time? I have heard they are fire magnets so it would seem it might be alright to have 2 for when the enemy shoots all their anti tank at them turn 1. Note I have also picked up a flamer helldrake for MEQ clearing but as I have yet to play a game this edition I am not sure how many template weapons I actually need. I am hoping they are fieldable since Vindicators seem great for an Iron Warriors army. Thanks in addvance for any tips and sorry for the wall of text.
