Hitting breakpoints doesn't "extend" your DoT, it makes the bomb tick more times in the same period than before. There is no "extra duration" to consider, the duration (more or less) remains the same, so you are gaining nothing but DPS by hitting breakpoints. In Single Target circumstances, bombs are doing ~25-30% of your damage. In multi-dot situations they are usually doing ~50-60%. Now, granted this is because Arcane is currently broken as hell and the only reason it's viable is because of the bomb buff. However, while this may be the case, playing Arcane at the moment IS playing around Bombs and how well you can manage them, especially in multi-target situations.
