Lenshu with its current ED has a vast variety of viable openers. Increasing it insignificantly wouldn't affect the game too much, it would only change how certain openers work against each other. Increasing it significantly would lead to popularity of camping openers due to players' inability to reach each other at opener stage and achieve point inequality.
Reducing dojosize will make aggressive play more rewarding while making passive play with running a bit less rewarding.
DQtimer change doesn't seem to affect anything.
DMs must be removed. They instantly end games, completely based on luck and are clearly too much to be a ''reward for a strong hit''. Points are enough of a reward for a strong hit.

If Lenshuf becomes a mod with smaller dojo and no dms, it will be superior to lenshu3ng in the most important ways(except you might say it's less ''fun'' w/o dms, though for me dms were always nothing but annoyance) especially for competetive games. It wouldn't have to completely replace lenshu3ng, some people enjoy bs, so for competetive servers like tourneys and ranked there could be Lenshuf and for fun servers like public7 there could still be lenshu3ng.

The problem with countering rush openers itself is only existent in low level or fun-oriented enviroment. Lenshu has a decently balanced rush/defense opener meta with its current ED.
Mods with changed point distribution were always poorly thought, subjective and fated to be outcast. Though I hate lenshu's leg points, I'd say it's better to refrain from changing point system for now.
