After reaching the ssj players dont really gain anything new.. just maybe a small PL boost and 1 or 2 new attacks...
What if you for each new transformation you earned, you could do an extra melee hit.
- If a player earned ssj1 that player can now do 3 basic melee hits in a row.
- if a player earned ssj2 that player can now do 4 basic melee hits in a row.
- if that player gained ssj3 that player can now do 5 basic melee hits in a row.
-Each hit costs the same amount of ki
-for each hit after the first 2 basic melee hits, the damage is reduced by 50%
-Since each hit after the first 2 is a weaker hit the player being hit can recover faster. Giving the player being hit the ability to catch an ssj off guard if he decides to wait until the last hit then recover really fast or if the ssj isnt accurate he could just recover after the 2nd hit.
-Advantges? Going ssj has it's real advantages now in combat. You can pull off great combos.
-disadvantages? Ssj's burn more ki if they go for the extra hits ( really.. is that a disadvantage for the person being hit?
-How is it real to the show? In the show when goku went ssj against a weaker opponent he landed more hits then his opponent "no doubt"
