Jareg as possible Tayrel replacement on CB team?

So I have Tayrel and he is a staple of my CB team. Let's face it ... Tayrel is one of the best epics in the game. He's great just about everywhere. I have enough food ready to take him from 5 stars to 6 stars and was all set to make him my second 6 star when I pulled Jareg, the new Lizardman epic.

I've got Jareg almost up to 50 now and am debating whether he should jump ahead of Tayrel as the next 6 star and step into Tayrel's role on my CB team. The main thing that Tayrel provides for CB is the attack down debuff on his A1 that helps prolong the fight for damage dealers to get more turns smacking the boss. Jareg provides this buff on his A1 as well (slightly lower proc rate with no skill tomes), but he also provides team defense up and some heal over time. These add a little more to the role of keeping the team in the fight longer.

​

My current CB healer is Steelskull (RIP Pain Keeper), and he provides the defense up as well and direct healing. I think Jareg might fit better alongside Steelskull to help keep 100% defense up and to fill in the healing gaps with his continuous heal.

​

Tayrel's other debuff is defense down on the boss. I also get that here and there from my team lead, Fu-shan. It's not 100% uptime, but I find that debuff on the boss to be slightly less important than team defense up.

​

Thoughts on this from you guys? Is it crazy to consider replacing Tayrel with Jareg? Is Tayrel the clear winner even without providing the team defense up and continuous heal?
