It must be raining somewhere else!
Honestly I don't see the appeal of Dreadnought. It provides significant defensive buffs and rare stats - and I understand people being draw to Rune King. But you are aware that Rihaku doesn't promote things because they would be the optimal build or even the best story, right? He's promoting it because it did relatively poorly prior to the consolidation vote, and has few voices for it.
The appeal of Dreadnought probably stems from three very understandable points:
1.) Depending on the choice, either regrowing our eye, or ridiculous magic system scaling. Both are immensely cool, one because the readers have come to care for Hunger and becoming whole again, and the other because holy shit can you imagine how cool it would be to master all the magic systems and synthesize them into a meta-magic system (or, knowing Rihaku, infinite cardinalities of magic systems?)
2.) Resisting Tired and Exhausted, making us less vulnerable overall (plus the benefits of ignoring Exotic Attacks through Con is actually quite powerful).
3.) Synergy with Iron Curtain and a massive stat boost (although not as large a boost as Stranglethorn, it sidesteps the loss of Agility, which some voters view to be important.)
Personally, I see Dreadnought as the next thing to take immediately after Stranglethorn. Their synergy is immense, the power is undeniable. Stacking a Constitution plus giving it amazing utility in blocking Exotic Attacks through a Con check is remarkably strong, and I want a second eye too. It's just that fights that give us 4 picks are remarkably rare, and Undying Vanguard lets us bring Gisena in. So unfortunately Thousand Cuts in my opinion has fallen by the wayside until we can pick these Stranglethorn and Dreadnought in that order (unless someone can convince me of Ruinous Valor to follow).
