for skill stocks u mean the stock for the dms?
edit> understood
ya reason why i don't like Ralf (L) is because his requirements for landing it is not as good imo... it's best to pick the character that can utilize their LDMs the most effective way... even if it isn't your best character...
i'll give you examples from my teams... Clark/K'/Kula... i'll use Kula as leader... Clark/Iori/Mai... i'll use Clark as leader... Clark/Ralf/Maxima... i'll use Maxima as leader...
the idea is to give your team a trump card... something that can be done out of most possibilities at minimum cost... or something that greatly diminishes a character's or team's weakness... or something that adds a new option for you...
i understand what u mean. But at least in my case i ll switch my leader as i like.
I tried the same combo (same as the video linked by mazinkaiser) with some different chars/leader:
tried clark-->adel (the damage with his leader was quite disappointed)
tried clark-->elizabeth (same as adel)
tried clark-->athena (i dont like her, i just wanted to see how was her L damage, and well, same as ralf= 100% (if u dreamcancel her air dm))
since i will never use athena, i will stick with my "switch leaders as i like". Ralf's LDm is easy to land anyway, i mean if u catch ur opponent with the "charge b,f A/C" u can dreamcancel and the damage is still good (also without changes). Adel's is good only out of a combo (just my opinion,eh).
Since i dont play at high level (like koreans or mexicans do) i will switch my leader every match xD
