Umm that's not how the Ork Mob Rule actually work. A WE is DC units IN a formation, not with other formations in a range getting a buff - that or your wording is odd and I am not understanding what you're actually meaning and if so, apologies and please clarify.
Also since that's a rule from the initial release of EA your claim of "replacing weakness with special rules" is spurious as it's one of the original 3 and hasn't been "buffed". In fact as one of the OG list rukles, it's the standard upon which we use to gugage any creep. Perhaps you're discussing actually one of the Ork variants under dev that has a tweak to the base rule (I can't say I'm up on all the sub variants like the Deathskullz or Sun-Tzork). However if that's the case it would lead me to say then that list would be the issue and not AMTL per say, and is likely why they're not approved yet (and good on ya for keeping that on our minds though can't really be used to say if an approved list is too weak-just that the other may be OP instead).
I'm with JS in that I too would I'd like to see more of those other weapons tried out in subsequent releases for tournament inclusion. Centerfire cannons, rubble claws getting CC buffs and being free (seriously, the speed hit is enough), wrecking ball, etc getting some wide validation for movement out of the Collectors section. Unfortunately as it's fairly fringe list (not a knock, just not that people have spent too much time building their titan forces up I suspect) it's not got enough wide range of tournament circuit peculation and metas and tactics are still adjusting I would hazard. Having only taken them out for a couple of games I don't have too much to chew on but get the gut feel they're middle of the road.
So in short, probably some tweaks here and there (more options and flexibility) but not hamstrung in that hands of a competent player. I do think they're more ill suited for the TP scenario than other lists but that's true of any "extreme" theme list in general and there's little more extreme than 5 titans on a table!
