Co-sign....heavily.......
......haha...still I don't mind, the juggy is taking on a lot of arrgo so it gives me time to take out lesser enemies while the focus is all on him.
That would all be well and good if they could stay on their damned feet. I can take advantage of an aggro magnet as well as the next guy, but a corpse isn't an aggro magnet. Don't ask me how they can fail at the kit so badly, but it's maybe 1 in 20 Puggernauts I see that can even stay on their feet.
And as to skipping shadow strike:
I do find that the power leads you into dangerous places that you don't always intend to go into, and the targets that can safely be striked, can usually also be dropped from a single cloak cycle anyway. Electric Slash is one of the best AOE shield strippers in the game (I'd have to check the numbers on the tech burst, but I think one slash is basically chain overload+arc grenades+tech burst, sadly with a max tagets of three), and a cloaked heavy melee from her with fire sword hits harder than a normal heavy melee from a warlord against armour.
With my build, I get 3k damage to shields an barriers on three enemies twice per cloak. It also feels like Electric Slash does the double-damage-against-Geth thing that electric attacks tend to do, 6k damage feels a lot closer to the carnage she causes Geth Shield. Heavy Melee from cloak does 3k damage to armour as well. There isn't a single geth unit short of a Prime (and fighting one of those just requires knowing your movement and damages) that wont die in a single cloak, whilst staggering his buddies (and/or destroying Geth turrets/drones).
Sadly, I take a weapon rail amp on Platinum instead of a Strength Enhancer, so my melee suffers and I have to play it safer. She is still a very nice shield stripper, and very capable on Platinum.
TL;DR Not saying I have the best shadow (I don't), just giving some of the reasons why Electric Slash is good enough to not be skipped. I've used both, even on the same build, I just find Shadow Strike problematic in the long run.
