Sadly that's not quite the argument - it's the two of them together. It's the lack of fidelity causing a CvC imbalance that's the issue. It's when one directly causes the other that I think you have an actionable issue, not merely for aesthetic balancing considerations. A short-range dimension door (Flee the Scene invocation) requires cover/concealment to really make good use, even with the major image - where it's relevant is in the ground that can be covered in the time it would take to pop off a walk unseen effect. It's not that warlocks can't go infinite on paper - it's just much harder and much more situational and they can be frequently put in awkward situations simply based on the path an escaping PC takes. Those problems really aren't quite the same here in the NWN2 format, both because of the haste effect and the infinite nature of warlocks (coupled to the abstract LOS system, invis system, and capped movement system among others).

All melee characters have infinite attacks (and multiple attacks per round) and all ranged warriors can stock up enough ammo to make ammunition moot for any given encounter. Plus, they get much better armor. A warlock has virtually no melee defense other than retreating.
I guess I just disagree - the question for me is to what extent the expendable resources of the PC are at risk. Melee characters have infinite attacks, but on general terms expose themselves to retaliation strikes. And, once you eliminate overwealth/over-AC conditions, there generally should be an exchange rate here. I would strongly not recommend trying to take on a 300+hp CR 18 thwacking mob with a solo 10th level fighter on +1/+2 gear, for example. Anyone want to take a guess how long that fighter lasts on 28 AC against a marilith? The warlock involves a decent-die attack at extreme range (Spear) with high hit percentage (ranged touch), and more than enough time to pull off the two escape abilities with sufficient planning. There are some limited options as stopgaps, but most are limited in scope. Ranged response is possible, but involves switching, targeting, etc. and is a marginal strategy - and many opponents do not have that option.
So in the end, I'm not sure how it constitutes "looking at a single scenario" to say that this mindless rinse-and-repeat technique against things without counters is presumed powergaming. I think a couple of technical tweaks to Flee the Scene would be helpful so that it's more - as intended - a retreat option than a party offensive buff, but in the meantime the only must-solve issue is the combo. Maybe that's not convincing enough to anyone. Maybe rezzes and/or IC ramifications will lead to a balance. In the end a hunted warlock is in a lot of trouble. But I think the characterization of this argument as trying to justify the existence of Standards or something is pretty thin. You may not buy it, but the argument's certainly colorable.
But here's a simple question from me - I think that use of the warlock is equally offensive to camping and ambushing off of an AT. If I saw a warlock doing that to me, ATing and camping it would be my instinctive response. Now the latter will get me a strike and a CvC reversal, so why wouldn't the former?
