Smash is terrible to hit. It misses more then half the time in pvp. Even if you standing at someone. In BG, so no cp, people are able to breakfree before they land. The knockback should be unbreakable like DK leap or fossilised.
Ideas for you:
Double its hit area and its range, more like cleave.
Halve the cost.
Refund the cost if no targets hit.
Here $15, goat mount please. Not gambling or paying 45 : lol :
20% base speed for high ping players.
Streak moves you faster then speed cap.
They should of made 4v4v4v4 instead of 8v8.
