Hey, I'm super glad you like it and I also hope that people are excited enough to modify, hack and create for the little system. Behind the scenes, I'm working on creating a mod-pack, to help kick-off content creation or just for hacking the system for house rules or whatever people feel like. I'll make an update post whenever I feel things are ready to be shared along with a road map of other expansions on the system, that I might proceed to work on in the future.
As for your critique, given that it's a roll-under system and only D6, I've kept the core Stats permanent after character creation, meaning that each player will have a stat that is max 4, one that is max 3 and one that is just 2, so at best, a roll will always have a 1/3 chance of failing. There are temporary boosts that i.e. give a "-1" to a single test roll, such as the condition "Bless" and one could have (rare) single-use items that also give such a boost, but the Loremaster should (in my opinion) very rarely allow such powerful manipulations, even for single rolls. I hope that answers your critique :)
