I just wanted to add one last thing. HTC has never told me to stop playing with the FX. When I changed the fire, explosions & smoke early this year, it was HT himself that started a PM conversation with me, helping me out with how the ground smoke system works. No one ever said players could ONLY add terrains to the game. If HTC happened to see anything I do and think it would be good for the game, they could gladly have it. Seeing it in-game (besides the AvA) would be thanks enough for me. That being said, when I do this stuff, I do it for enjoyment. I have never submitted anything that I thought mine was better than the default. 
I didn't mean to put you on the defensive by any means so please don't take my comments wrong. I was simply stating my own personal opinion. Maybe where I went wrong was my cautionary warning but in all the years I've been here the tendancy of the players has been to encourage every graphics change, good or bad (not saying your's are bad), when an environment of open, constructive criticizm might better serve the community. As an example:
After posting last night I was thinking about your explosion graphic and my capturing screenshots after scenarios. As I do so and slow-mo through explosions they generally start with a hit sprite folllowed by an orange expolsion surrounded by black smoke then transition to a bright yellow expolsion with white smoke then an all white explosion that dissipates. As I said there's things I like about what you posted but wonder where it fits in this sequence or if the entire thing is completely different. For my part (and my part only) it would be hard to agree to a change without better understanding the entire sequence of graphic changes and then seeing what that looks like in real time in the game. The current sequence happens so fast in the game that I doubt most even realize how much went into that one effect.
