Simpler? Sure, but ask any Warlock main and we can certainly tell you it was not "better" to be stuck on Well of Radiance instead of literally any other super. The only time we got a reprieve was if it was one of the challenge runs for the same subclass or maybe if there was already another Warlock in the fireteam running it, but even then we usually had to chain it. Bungie had trouble with designing encounters around the super, which led to higher health pools and gating health. Sadly they have not backed off of the former but slowly they are getting rid of the latter.
