[Sandbox] High-Explosive Shells Revision: Join the Testing!

Falathi: Guys,  just a short reminder as we`re effectively waiting to see the results of the test: 
 This is a Sandbox. Changes tested in Sandbox are usually pretty serious because we want to check how the game would look like and what the results of some serious changes would be. How would they affect the game? 
And the key point is: it is a Sandbox. Some things tested here made it into the live server after the test results were satisfactory. Some were scrapped altogether. It is too early to say that yes, these changes will be implemented as they can be scrapped, or changed. I understand the concerns, but guys - it`s really a bit too early to say for sure how this will affect the live server as it may or may not happen at all.
