I've gotten this addressed now with the new build that I released today-- you can now switch between hold to aim and toggle to aim in the input settings.
I noticed already, did not expect it that fast xD, feels very nice :)
Sad that there is not much left to do with my already lvl 10 fighter, and 16 mystic xD, but will certainly look forward to taking full advantage of it, for any future content :)
