Nah, I'd probably...
train vis+conf now
switch to agi+vis after confidence gets to 33 in training (vis will be way behind conf)
switch to agi+spd after vis gets to 33 in training
take agi to 49, now train agi+spd or agi+sta, whichever is lower, to keep spd and sta close together
now take agi to 60, and switch to spd/sta which you strategically trained to be lined up as your final pair
I really plan out my training and make sure I hit EVERYTHING from as low as possible to 34, incorporating training at 49, etc. I don't advise low agility. I just see no reason to rush into training it at level 13 when confidence is getting 0.67 per level-up.
Anyway yeah, smart training plans can be just as valuable as smart cap-building... I see way too many players who look like this (or something similar, this is to make a point)
70 agi, 25 vis, 15 spd, 35 sta, 40 conf
Uuuuh how are you going to train speed? Agility at 70? Stamina at 38? Cap stamina and keep training it? LOL. How about vision? Cap conf and keep going there?
And they end up with those numbers because they read a slowbuild guide that said
"train agi+sta until they are at 33 each. bring agi to 68 and switch training to vis+conf."
Meanwhile speed is nowhere, and confidence gained so fast compared to vision that vision is left in the hole.
the most important training is at level 40, not at level 15. Everybody has a good pair to train at level 15. I'd argue less than 10% of current level 40+ players have a valuable pair.
