I was in a similar situation a few months ago and was all set to give Quintus my next set of tabards. Then I drew Zulag and decided to hold off and give them to her instead, since I needed a tank. Then at Christmas, Krampus showed up, beat up my Quintus 3^70, took his lunch money, and put him on notice that all sorcerer emblems would be his personal property for the foreseeable future. So I’m no longer in that situation, but I think your line of reasoning makes some sense. I was hoping to get to try C. Rigard + C. Tiburtus + Quintus w/ emblems to see if it just decimated a raid defense. Probably be a while before I get to test it now - if ever - but you’ve got the personnel to try it if you choose Quintus.
How much summoning do you typically do? As FTP, I’m naturally inclined to level and use heroes that other folks wouldn’t give the time of day. Using the heroes you have is fun. Sitting on mats hoping for better heroes to show up is not (says the dude with a Thorne +16 that he uses on the reg.) HA 10 has given me a bit more pause, since the next great thing could be less than a week away, but even that’s a long shot. If you are doing a fair bit of summoning, waiting until you have more tabards has some merit. If you know you aren’t doing many pulls for a while yet, don’t overlook some of those “lesser” heroes. They have their uses.
Even three-stars? Before Krampus showed up, I took Chochin to +19, and I was all ready to do Gill-Ra and even Jahangir as well. If you aren’t sold on your five-star options in a class, might as well build up some depth for events and certain raid tourneys. They go fast and are cheaper. Did this with my barbarians also, since I wasn’t sold on Azlar. Now, I have a Nordri +20 for titans, an Azar +c19, a Nashgar +19, and a Namahage +11; the latter three were part of an A defense in last week’s raid tournament.
With the current minion meta, I also think Grimble might deserve more consideration than he’s getting.
Heck, before I was giving Sartana emblems, I couldn’t justify her over my Domitia +18. Unemblemed, she just isn’t a “king of the mountain” sniper like she was pre-emblems. Mine is at +12, and she gets a ton of work now, but without emblems, I found her underwhelming.
