I think they just summed it up really badly. At the end of an IGN score, you've got compliments and criticisms at the bottom, summed up in short sentences.

'over-reliance on Water Pokémon' or 'some routes are boringly easy' would both be infinitely better sentences than 'too much water', which on the face of it, and without context, does sound like a bullshit bullet point.
