It gets extremely boring, and their choice of sticking to the originals made most of the Pokedex absolute garbage.
>only physical moves Farfetch'd learns are Sky Attack at level 40 or Fly>the ONLY physical water move Kingler learns is Crabhammer at level 42, otherwise you're stuck with Bubblebeam>one of my favourite mons Venomoth doesn't even learn poison moves through level up, and the only special bug move it learns is Bug Buzz at 46If you want to actually level your Pokemon you are forced to catch Pokemon. For instance I just beat Koga and his level 43 Weezing and Muk give around 650 EXP each, I can just go to the next route and catch a Pokemon on the first throw to get more than that.
This game is actually more of a grind than any other, and it's novelty is worn off as early as the third gym. It's a chore even wanting to go and finish it now.
>>37266124I was chaining Psyduck and had one run away after the first ball throw which apparently is not supposed to happen, every other chain is broken by mons fleeing after two excellent throws. Not to mention how many times that exact scenario you mentioned happens.
