Ad 1 Will You compare amount of preparations required for using for example Wicked Wines with All Together Now? And even markers spamming, which I believe I already said, but seems that nobody of You read so here it goes again: 0 actions for dropping marker but requires distance 4" from another, so You need to move or use mannequin - hire mannequin, activate mannequin, activate mannequin's ability, survive with mannequin until another activation and so on. Slightly different than just go in range and use ability.Besides how many markers can You really throw in Colette's 8' bubble? Remember about 4" distance of each other and keep in mind that throwing markers behind is mostly useless.
Ad 2 At least it is not a free SS any more... Ok, free suit BUT it is still under condition: You need to have at least 1 SS left. If there happen that You will need to use all SS early in the game this ability is gone.
AD 3 Never said that Prompt is useless now so this argument cannot be invalid since there never was one. I already wrote what could make it more balanced: reduce multiple prompt to showgirls only (single prompt per turn for any other models). Since when Colette has free dove every turn? Is that ability printed on card and then it's cost is 0? Does it not require spending AP? Does it not require quite high card and suit? Do Colette has free suits anytime without any conditions to summon doves?
Prompt was overused because it was easiest and most versatile ability Colette had. Other Abilities are too situational and/or resource draining. It is as simple as that.
Comparing Prompt and Obey is pretty much pointless since these abilities are different: Obey may be cast on enemy models as well. Prompt is limited to friendlies only.
Why prompting Coryphee is worse than Langston? Everybody were complaining about Langston prompt, not Coryphee prompt. There must be reason why. Maybe because Coryphee is a disruptor and not a killer (no abilites that could ignore Hard To Wound, Hard to Kill etc). Maybe because it's quite fragile - conditions kills Coryphee quite easily, 7 wd for 14SS model...
Your last phrases are quite sad, it states: who am I to discuss. Sounds like I should shut up and agree with elder and smarter. That's the reason of forum existence, isn't it? Why instead You give me some ideas how to utilize effectively other abilities considering it's high cost in SS, AP, high cards and suits? That would work so much better than calling on experienced players authority.
Also telling that some argument is invalid does not make it invalid. Proving it does.
