Spell cascade area of effect problem

The flame wall, supported by a fortress and a spell cascade makes the circles smaller at their position. Which is fine, but it would feel better if the cascades happened closer to the center whenever the player has negative area effects. The circles may interfere if there are a lot of positive area modifiers as well. I know it wouldn't look as bad if I didnt use fortress.

This probably works like this with other skills as well, so maybe spell cascade needs to be adjusted.

Also this is a very small thing and most likely wont be fixed, but I'd like to mention it anyways
