I disagree that you can pass on repaints. In the case f piccolo specifically, his manga coloured version is not piccolo to me. Not having the familiar appearance of my favourite character, that's what could make me stop collecting (and it has, by coincidence ML's among other things, because those aholes refuse to make jim lee cyclops).
I find the 'completionist or not collect at all' stance really weird. I just don't get that, at all. I get wanting to be a completionist obviously, but I don't get dropping the whole thing if you miss one. It seems to imply you only care about checking off a list instead of having your favourite characters embodied on your shelf...? I'm not saying that's the case, but if it isn't, how could you part with them just because you don't have a character you might not even care much about? That makes no sense to me whatsoever. Also, what's the fun in being a completionist if there's nothing hard to get? Isn't the effort in completing the whole point of being a completionist? Having 'piece-de-resistance's so to speak?
I'd like Sdcc ex's to be either special versions (which mostly boils down to battle damaged versions) or special impressive side characters. No more main common appearance characters for an exclusive price, of all things stated, that's what sucks the most imo.
