I just want to be upfront and say I know this is an incredibly minor issue but, I notice it every day when I play.
When you evolve, you see big bubbles and growth effects sprouting up and popping all over your monster. These effects always take on the colors of the default skin for your chosen monster’s species regardless of what skin you decide to equip that match.
It would be really nice if these effects better reflected the colors of your monster skin. Again, this is a very small issue and most people probably don’t care because there are much larger fish to fry right now in-game but still. If they can code Behemoth’s rock form to reflect his skin it would be nice if they could update this.
On a side note, it would be great if monster glow changed with the monster’s skin. Take Goliath’s eyes as an example, on Cosmic his eyes are blue so wouldn’t it look sexy if his purple skin had a blue glow? His Bog skin has green eyes, it would look fantastic if that skin had a green glow to match.
