You get Paragon so long as you have 3, get the title, then rank one down
Go check Brian Grant latest vis, para-gone. If you are thinking of r4 Moleman then rank him down.
Could you please try this for science? You wouldn't be losing anything
I have a r4 herc and took moleman to r4 to test out. Decided I wasn't pleased, took him back to r3 and ranked Apoc to r4. So I had 3 r4s in total but only 2 at this moment. Also have act 7 100%. Still no paragon. Hope this helps.
Can you get paragon with 2 rank 4 6* and 1 7* ? Since 7* entered the game it should be a possibility to easily obtain the paragon
