Not at all, I probably would if seeing what the IV's were was possible without having to seek out something to tell me what they are, as for EV's i just sorta play the game so really dont pay attention
I think that getting good stats are a part of the challenge in the game. I hate EV-training though; I wished they had come up with something better, that didn't force you to fight hundreds of weak and easily defeated Pokemon.
Well, back when I was a wee lad with Pokemon Blue, I didn't really even know what stats were, or what they were used for. So I just ignored them. However, when Generation 4 came out, I began to see the significance of what stats were and what they did. So now I pay heavy attention as to what my Pokemon's strengths and weaknesses are by use of stats
Being mathematically minded, it irks me to no end if my Pokemon are lacking in essential IV or EV values. At least, it does if it's a Pokemon I plan on using. If it's a Pokemon I'm catching for Dex completion, I don't really sweat it too much since I'll wind up releasing it anyway.
