It's hard to analyse without the other details of your build, but your strategy does sound a bit... disjointed.
With trigger selection you want to use conditions that come up commonly in your battles that you want to take advantage of or find a workaround for a particular weakness.
I suggest you start simple and get your first line or two working well as your "bread and butter" attacks and then start adding in other lines one at a time and see how they work.
With rage, keep in mind they are strong out of the gate, but are open to a beating when they get tired.
I suggest you try something like:
1) Start of battle/standby: Berserk 8/6 and play with your activity/bloodlust to get something that works.

With the other lines, think of what conditions you want to change things at - sometimes thinking of it in terms of the battle progression helps (instead of just as single elements). Keep in mind that the higher the strategy is in the line order, it will take priority over the lower line strategies if the condition is true. Try picking one particular group, like health, or endurance, or activity levels and taking a couple elements out of there to work with (for example, increasing your activity and/or bloodlust as you go down in health). If that works out well, then add in another from that or another group and see how that works for you.
