Searching for Ralts on Route 102 is such a pain, I managed to catch a Timid nature Ralts though i'd prefer to have one with a Modest Nature?

I haven't progressed at all in the game since Yesterday. Should I just use my Timid Ralts for my playthrough? I'd prefer to have pokemon have not have the exact same nature and I plan on using an Timid Electrode later on?

also another quick question, how do you increase the DexNav search level, it's still only at level 1.

seriously Ralts encounter rate is frustrating me.
