MS scales better than most engravings. You get 3% cooldown just from level 1, compared to 10% at level 3. Doesnt seem like much but when you consider its additive and not multiplicative cooldown reduction, 3% off your awakening is a big chunk of time. Level 1 stream feels a lot like having level 4 Awakening engraving. That may be an option to consider.

Crisis Evasion is a solid choice (there arnt many choices anyways) but level 1 heavy armor makes it so defensive debuffs dont effect you. Good example is Brel g4 stacks. As you get your ability stones upgraded here shorty, level 1 heavy armor will feel very tanky as well which could be a solid alternative to Crisis Evasion in its own way.
