I'm sorry that you find it hard to distingush between two strings of english characters, but I don't think it's a good argument for keeping the species clause.
That's a ridiculously childish retort and I'm sure you know it. Its not a matter of "oh but i have to REAAAD :((((((", its that what a Pokemon is nicknamed really should not be directly related to the competitive aspect of the battle.
To summarise so far, the main arguments about the species clause itself have been "But I'll have to guess a moveset" which is no different from any other pokemon, and "I don't know if they're running two of the same pokemon or not" which essentially means that at the start of a match when you have seen 1 pokemon on the opponent's side, you must now guess from n+1 instead of n, where N is the number of pokemon the opponent might have not including the pokemon you have seen. N+2 when you have seen 2, and so on. I guess it just means that the number of pokemon you have to guess for each slot never decreases, but is probably an overall difference of about 1% more pokemon you have to consider, maybe?
Aaaaaand you're still not really getting it, or at least not acknowledging the problem. The guessing you have to do doesn't reduce at all until you've seen all six Pokemon, because that sixth Pokemon could be the same as any of the five you've already seen. I think that's what you were getting it, yet you still say stuff like "the main arguments about the species clause itself have been "But I'll have to guess a moveset" which is no different from any other pokemon" which is completely ignoring the whole issue. Despite what you seem to think, it
is completely different to the predictions we have to make now. Because each time a Pokemon comes out, you have to make two guesses: "Is it the same one?" and "What moveset does it have?". Getting the first prediction wrong (assuming it is the same one when it isn't, or vice-versa) can screw you. If you get the first prediction right, you can be still be screwed if you get the second one wrong and switch in the wrong counter. That's two
blind guesses on the
same turn. That's nothing like what we have now and you're not furthering your case by dismissing that fact.
Obi's got a point about damaging a Pokemon to identify it, but its not that simple. When I bring my Bronzong out against a CB Salamence using Dragon Claw, that Salamence is retreating straight away. If they bring Salamence out again, and I switch to Bronzong again... This time to find its a SpecsMence with Fire Blast, then I got screwed because I didn't have a chance to differentiate between the two. Even if Bronzong sets up Stealth Rock after the first time it comes in, no matter which of the two variations come in next, they're going to be down 25%. The only way this would work is if I set up SR before the first 'Mence comes in.
I know Stealth Rock is hardly a rare move anyway, but to easily identify duplicates it pretty much needs to be set up on the very first turn (or as close to it as possible). And if the opponent's lead is the same Pokemon they have doubles of, you're screwed either way.
