It seems we are in disagreement. I do quite the opposite, find a build I’m comfortable and seek out the desired COM, while leveling you’re constantly picking up new and better COMs, I might respec at will but not based on a COM alone. For example if I have a low level green Binder COM and I pick up a blue Witch, I’m not about to respec based on that COM alone as the skills and stats on that COM may not be desirable, and the Witch COM hardly is.
This is somewhat true, but on the contrary you’re not typically taking heavy enough damage in TVHM for survival skills to be necessary either. Sweet Release for example will only proc on a kill, and if you have trouble killing a badass you can’t reap the benefits. Against trash mobs either way works just as well, but against badasses you may find yourself pinned down and in a DPS race, and Ruin almost always wins that race.
Unless you have Suspension, Phaselock also only lasts five seconds, and that’s all you need in TVHM. As for weak points, Helios since the buff is a very powerful skill, unfortunately it procs before Ruin but the shock and corrosive DoT on Ruin after slag deal a lot of damage through TVHM. It’s also nice as a damage dealer and auto slag against enemies that can’t be Phaselocked such as bosses.
But each to their own, it’s more about preference over effectiveness early game it’s not really until late TVHM-early UVHM that a build really starts to take shape, by then you can have Ruin and Converge anyway. I still stand by Ruin at 31.
