Playing Omega Ruby. Just took out the fifth gym, heading to six.
I don't like this game, I haven't ever needed to trade a Pokemon team over from another game because grinding for exp was a pain, but it is in OR.
Try to grind after catching your Pokemon in the last area but the Pokemon in the new area all.seem to have some sort of advantage in type over you l, meaning you walk back to a pokecentre after every fight or burn through your cash on heal items.
Catch Pokemon in the new area and they're not effective when grinding on it and the next area has the same problem of having an advantage or status changers.
Its really annoying.
I've had to trade over two different teams so far from my completed Y save just to cut out the sheer irritation of actually hunting, training and catching... Which isn't good.
I missed Ruby the first time around (and diamond,pearl and black/white2 [and didn't finish black because it was crap]) and I'm kind of wishing I missed it this time too.
