My first response would be to spend time on being a better fighter by working on fighting.

Second you are going to make the most progress and get the most carryover in the initial improvement you get from adding in intervals, heavy weight training, BJJ, etc.

But last week somebody posted about losing identity from no longer having sports related goals to train to...so if you are training for health and general well being and setting a goal inside your own training increasing form 2x to 2.5x dl is great if it gets you in the gym.
