I haven't compared directly with the previous numbers, but we're overall making 3 star evo shards drop more commonly, then making it so coloured is more common than colourless (instead of the other way around). I think on average you'll get about as much as you currently will?..
Yeah, we're looking at multiple avenues of better easing new players into evolving their first character to 5 star, but we still want it to be a satisfying milestone to achieve. This is just the first step of a few things we have planned, and there's other tuning changes we're adding in the next update to help address this too, with more coming later.
