28 more attack 15 more magic attack 44 more defense 16 more magic defense 8 more ... *I forget what this one is hehe* 38 more evade
Since captured monsters are = to evolved asap monsters (after they gain a level, which I have verified myself on previous monsters) we can see what a boost you are getting from maxing a character vs morphing it right away...
effectively that is like having a monster that is 10-14 levels above what it would otherwise be... and the gain for tier 3 must be similar
so its more than a few points, its actually quite important... 28 more attack is HUGE... by tier 3 it will be massive
I can also confirm that all monster stats are fixed by monster type, the ONLY variance comes from when they have been evolved and what they have been fed
now of course IMO stat maxing isn't necessary, but some of us care :P --- i7 2600k 5.4 (!) GHZ | H70 Hydro Cooling | 1TB SATA3 6GB/S HHD | 8 GB DDR3-1600 Dominator Ram | AMD Radeon HD 6970 | 850W Power
wow. that makes tier 2 monsters next to worthless to capture. Wow.
Well as was said, this is only really relevant if you want to be uber-God-tier at the end of the game. The actual game isn't nearly difficult enough to REQUIRE the kind of stat-management this revelation would be useful for.
Still a nice find though, for those who do choose to take advantage of it.
