This discussion seems like it's going pretty well. It does open up a lot more options in terms of arranging games, etc.
Talking long term here... If we end up adopting it for most BG tournaments something that I have to consider is the impact it may or may not have on people buying models. Discouraging people from buying the stuff they might want, for any reason, is not something I'm interested in at all.
A guy being like, "I really want to buy that 2nd or 3rd Riptide but if I do it'll mess up my Komp. I guess I'll have to get stealth suits, that I don't really like or want, because it doesn't cost me a point." is terrible, especially long term. This also doesn't factor in that GW is making it harder and harder for BG to get (and make money on) less popular items.
Selling a dude 5+ Wave Serpents is something I like doing. That happens because they're good and help people win events. If what helps people win events is to use a unit of everything they already have, that's less than ideal.
Might it lead to people buying one unit of this and one unit of that? Perhaps, but I don't really see it happening the same way people want 3+ Nightscythes, 2+ Riptides, 230480923402934709243 Broadsides, 5+ Waveserpents, 3+ units of Wraithguard, 3+ Warwalkers, 30+ Jetbikes, 30+ SM Bikes, 3+ FMCs, etc. etc.
