User blog comment:Mich, Michele & Kuhla/Future Units Preview/@comment-26812357-20160129162410/@comment-4116965-20160130095552

Just a suggestion - never throws a certain unit, they might just be useful in the future.

I've thrown 4* star melchio once, because I judge a unit by its character & I don't want evil units. But when I saw him getting a 7* & he's siding the humans now, I started to regret it. But luckily, I got him again in his 5* form.

I agree with you for darvanshel, can't wait for his def buffs.
