So?

There are several Scrappers who can solo at +4/x8 missions (maximum difficulty) save for a few problematic enemy groups such as Arachnos or Rularuu. Cimerorans and Rikti are doable, though.

Yes.

The Illusion Controller is a support class, and even though he may be capable of soloing everything, he shouldn't run off and leave his teammates without the mitigation he provides through his control and the buffs/debuffs from his secondary.

The Scrapper (especially /Shield), on the other hand, doesn't provide much in the way of support, and actually works better as a separate entity. I would even say that his main contribution to the mission is to run off and clear his own area of the map. That way he doesn't have to deal with some trigger happy controller who uses his AoE immobilizes before the mobs are tightly packed around said /Shield Scrapper, which would lower the benefit from AAO, or be too spread out for the radius of S-Charge or any other AoEs he may have (Scrapper AoEs have tiny radiuses), or the slowpoke Tanker who complains that the Scrapper gets to the mob first and grabs more aggro than him, or the opposite overly aggressive Blaster who nukes the spawn before the Scrapper can get to it.

So in conclusion:
Good Idea: A Scrapper running off to solo the map and clear everything
Bad Idea: A support class running off to solo, leaving his teammates without his buffs/debuffs

Fully saturated Soul Drain + Against All Odds can reach greater +damage numbers than any other Tanker build, and the [Smite > Midnight > Smite > Siphon] chain is (afaik) the higest possbile ST chain for a Tanker

Hmm.

We can probably go on and on on an endless loop of repetition and redundancy

I think you might've misunderstood me

Prego

With this description, I'm inclined to think the devs will go for it. After all, they do hate villains

Killing a GM with an Ill/Rad isn't a challenge

Don't forget Corruptors, Masterminds and Dominators.

Also if you're fixated on making a Tanker for killing AVs, I'd recommend Shield/Dark.

This.

Statesman does shout "FOR LIBERTY" in the final mission of the LRSF.

Then again, given the context it may not sound as cheesy and cliche-ish, but the intention is there

Except your analogy, while humorous, is very erroneous.

If you use your face as a bat, you cause injuries to yourself, and you don't succeed in your objective (which is presumably to win the baseball game)

If you recruit a tank, a healer and 6 DPS, you don't hurt yourself, and on the contrary you have a very solid team to face almost any challenge.

A more accurate analogy would be if someone insists on just bunting the ball. Bunting can be a very effective and valid strategy in certain cases, but it's not the most desirable way to hit a ball.

Now I won't disagree with you saying that there are also more valid ways to build a team, but I just don't see what all the noise and what all the hate against "The Holy Trinity" is about. It's obviously an effective playstyle that has become legendary for a reason, and apparently this is the only game where it's frowned upon by the forum community (a very vocal minority).

You don't like how someone else builds a team? don't join them, assemble your own. When you try to "educate" other players, no matter how geniunely good your intentions are, you'll always come off as a pedantic know-it-all who doesn't tolerate other people's playstyle (and sadly that seems to be the norm on the forums)

My suggestion? just let them bunt all they want, less headaches for you
