I would rather see Tudor vs Midland on a more equal footing. It is not like Guts was always the ultimate badass by a large margin.
Guts vs Basuso, close.
Guts vs Lord Adon, not so close but still Adon was a more worthy opponent than most.
Guts vs Samson (Adon's brother), Guts had to protect Casca but he was still a fierce opponent, if not a Guts Killer.
Guts vs Lord Bascon, too close, Guts would have died without Zodd.
Also do not forget Tudor had Zodd on their side at one point!
A mode which was more like battle but where the top players were able to spawn as special characters would be epic.
A random 3 "champions" each match or something per team. No idea how possible but it would be awesome if it was!
