Interesting stuff.
Another example just to think out of the box, could be a Good-aligned Warlock with a Fiend pact. Is that impossible? The concept is clearly grounded on a Faust-ian pact. But how about a Good character who had a moment of weakness (or desperation, out of a tragedy) and sold his soul to a Fiend? Pact is made, benefits will be conferred to the PC, and the price is already paid. No need for the PC to act evil to please the Fiend, which already got his part of the deal. Maybe the PC will spend all his life regretting the pact, and yet exploiting its benefits (thinking that anyway there's no way to revert the pact) but trying to use them for a good cause.
According to the Monster Manual, when you sell your soul to a devil there is no way to get it back short of divine intervention, so the scenario you described makes perfect sense by the book. Sounds like a great way for a powerful enough devil to get a soul--just offer to make someone a warlock. Once they sign on the dotted line, you can pretty much ignore them for the rest of their insignificant mortal life, knowing your paycheck is coming in the near future (to your immortal viewpoint).
I agree that would be pretty cool as a character concept.
If you're a being dwelling on the far side of reality, then common sense and logic do not apply to you and the impossible becomes possible. The description of the GOO pact highlights the crazy nature of these beings rather well IMHOGood point; there's no way to make a pact with a being who's unaware of your existence. The technical term for this is "crappy writing" and it shouldn't have gotten past the PHB editors. The whole warlock section reads rather badly, IMHO.
I don't think you get a free attack if someone approaches you. You only get one if someone move more than 5 feet within you reach (walking around you).
I completely agree, it is a very good thing that the PHB doesn't get into too much details on how & why the characters get their powers. See for example Bards and Druids, the description of the origin of their spellcasting capabilities is flavorful but not too specific to the point of becoming limiting.
I do not have a problem with Great Old One warlocks needing to find a way to explain how their 'pact' works or what it really is... that's part of the fun! And if the player doesn't find an explanation, that's still ok with me, I'll take it so that the character isn't capable of fully explaining it either
I am very flexible with this stuff... In the past I used to tell Clerics players that there was even a chance their deity didn't really exist, and that the source of their spellcasting powers could be wholly in their faith. Who knows?

Cool. I like the things they're playing with.
Tunnel Fighter looks over powered.
What bugs me and im surprised i didn't notice this any sooner is the stupid revival ability is ripped straight from destiny right down to the last keystroke. This makes me a sad panda.
I've seen several posts that the tunnel fighter looks OP, and that that warlock looks OP. I'm always leery of making a call based on a skimming. Do we have any actual play examples? How often does the AoO come into play with the tunnel fighter? For example, compared to the other styles that have a meaningful impact nearly every combat round, if the tunnel fighter's ability only applies in one out of every six or seven rounds, that doesn't seem too OP to me.
