Because the sequel is still developed by the same team, with Jeff left the team(who believes his broken physics engine should decide players input command over players themselves) now this game is slightly better, but the team still adopted the same donkey philosophy.
They believe defender should work harder to fence off spamable offense attempt while all the risks are on defenders side. which made all spamming offense attempts with no worries & no risks
The problem with clinch isn't just damage and superior position.
1. it has no deny, that's utterly wrong in the first place 2. it can easily transit into other cheesy position such as piggy back, stand up guillotine etc with very little effort.
Dev of UFC games got the balance philosophy the completely opposite, offenders of sub & take downs should work harder/smarter, time it better to get it. and should have something to lose(say stamina and body part duration tax) when attempt failed. But now, these moves don't take more than 2 brain cells to execute and have no risk mechanic whatsoever to prevent them from using over and over.
No matter how good you are, these moves are extremely hard to fence off and very risky if you got into one.
