While I understand the disappointment, do you notice just how her attack animations can be laggy/slow? If you are building a fast paced fighting guild, from my observations, most slow attacking characters don't reach such a high competitive tier. Casually its still great, not in hardcore competitive however.
From the way you interpreted "Pikachu but with flying press", after watching the trailer again, I disagree with that. Rather, it's a Hasty Generalization on your part as to how I see it. Just for a small example, let's see her basic light attacks vs regular Pikachu's light attacks. Pika Libre has like 2-4 combos that don't respond fast. Regular Chu, on the other hand, has 5-6 combos with very fast attack animation but deals little to mediocre damage. The fighting of the two differs quite a lot. I mean, regular pikachu does not use electroweb at all from what's shown so far. Pika Libre has it on her however, and it causes a stat down if I recall the trailer.
