I do see where your are coming from Critical_Error, and yes an additional 2 seconds can definitely be very helpful, however, with a game mechanic such as ours, a fast paced game, we need to have some sort of draw back as you get stronger. Again, yes 2 seconds is very little, but you also have to understand to code in something such as that is also a lot of work. When our time can be spent more wisely elsewhere in the development.
We have been playing and beta testing ESF:Final for a very long time and it sounds to me that your assumptions of going SSJ3 means you can only play as that form for seconds. So basically, you are arguing over something you have no proven knowledge of.
You do have an idea and a team member, I am heartedly reading your post and trying to see this mechanic from your point of view. I will finish this post saying that we will not implement your idea solely because you are arguing over something you have no proven knowledge of "how much ki is burned off while being ascended"
