I keep seeing this in threads, or something that amounts to this: "MtK's stats are going to be +2-4 better because you have to factor in support that troll players take anyways".
This bothers me for a number of reasons, which I'll go into, but I want to hear other trollbloods' players opinions on the matter.
"Don't spend points to make something bad less bad, spend them to make something good more good". This is a maxim of competitive list building in ... basically every game, ever played by me. In the list-building stage, you need to decide if MtK is going to max offense, max defense, or play middle-road. Max offense is Mtk+Mauler+KSB+UA for 33 pts. This isn't too prohibitive a cost, but it does leave MtK vulnerable to getting 1-rounded. Troll players also have to ask themselves that if they're running this way, whether MtK offers significantly more to the list than Mulg. I actually think this is the most efficient way to run him, feel free to disagree.
Middle-road can basically be KSB+UA+Slag/Pyre+Janissa; not capitalizing on transmute but having limited base protection with the wall vs non-reach infantry and P&S22/ARM21.
Max defense is far more intensive: MtK + Janissa + EBDT + KSB+UA + whelps/thrullg is ballpark 40 points. This has to be your 'Janissa' list, and quite frankly there's only enough points left for Fenns+UA and Slag/Pyre for a damage buff. This is the issue I have with people saying 'you're going to take that support anyways': #1, no we're generally not. KSB is not in every troll list, Janissa/whelps are definitely not in every trolls list, and when they are in a list they tend to benefit 2-3 beasts and 2+ units; the cost is diluted by applying to a wider array of models. IMO this list actually offers less to MtK for defense because your screen has no back-up so you're either overextending yourself, leaving MtK behind, or more probably absorbing the charge and playing reactively. pDoomy can do this pretty well, but at this point we stop playing to Trollbloods' strengths and start playing to prop up Mountain King.
The final issue is how MtK generally forces beast brick warlocks to 'give up' something good if they want to utilize him. Everyone will give up at least 1 animus just by having MtK in a list, but Borka, pMaddy, p/eDoomy will also all lose some of their utility via feats and goad. They'll gain some too with a giant immovable base, but that much force concentration also has minuses (like inability to scrub upkeeps vs Crippling Grasp/Parasite on MtK).
Those are my initial thoughts, and ultimately it's going to be the tabletop that decides where this thing lies on the Animanatrax-Molik Karn spectrum. I am interested if you think there's more lipstick on this pig.
