I didn't say the scarab+ 30 engineers is unstoppable. But try doing your thing with the wolverines on Glacial ravine when the scarab can just retreat back into the cliff. ON THAT LEVEL the scarab is waaayyy too powerful. Plus you have to keep moving your wolverines around, which is a logistical nightmare. Almost as bad as cobras. My experience is that they almost always attack on the left first. But even if you have everything set up, if he's paying attention he can just pull his scarab back and your wolverines can't do a *** thing. Then he can walk along the cliff and attack somewhere else, possibly destroying a base before you get there. The scarab isn't unbalanced, THAT LEVEL IS.
wolverines> scarab+ 30 engineers= True... EXCEPT ON GLACIAL RAVINE.
You can try to attack them with vampires but once the engineers start healing themselves it will take forever. Not to mention if the scarab is in the cliffs nothing else can attack him, so he'll just shoot down your vampires. The mac blast is great... if you can hit him. The problem is that you'll miss with at least two of the blasts if you're playing anyone who is decent and is paying attention. And if you don't kill it it will be healed instantaneously, and it will have another, (what THREE?), minutes free range to destroy your bases.
As far as having two cutters... That seems stupid. You wouldn't have any decent units besides ODSTs.
Generally cutter can eat scarabs by surrounding it with ODSTs then mac blasting it. But you can't do that on glacial ravine.
I bet you could do it easily with a cutter/anders combo. The ice bomb would probably kill most of the engineers and would keep the scarab still while you mac blasted it. Plus it wouldn't take any units, just leader powers. Now all I have to do is convince my Forge to switch to Anders.
Then again maybe my friends are just incompetent because my job is usually to get up vampires, and I can relatively successfully get the engineers off the scarab, but they can't seem to kill it. Then they blame me. I'm pretty sure IT'S CUTTER'S JOB TO KILL THE SCARAB. Come to think of it... yeah... I'm pretty sure they're the ones doing something wrong. I play as the arbiter, so I can eat scarabs all day as long as there is only one of them, and combined with cutter we can take out two. But not if they're up on a **** cliff.
The scarabs are fine. JUST MAKE IT SO THEY CAN'T FIRE WHILE THEY ARE ON THE CLIFF. That would be perfect. They would still have the huge mobility asset, but it would actually take a little skill to take out your enemies bases because you would have to come down from the cliff momentarily.
Scarabs are a pretty overpowered in 3v3 if you are incompetent enough to let your enemies build four of them. But if you think it's a good idea to just leave two covenant alone when you haven't seen them build any units, then you shouldn't be playing strategy games.
I'm pretty sure 6 scarabs would be literally unstoppable, because you would have 30 engineers as well. But I'm also pretty sure that's never happened in any serious game. Maybe some generals have done it to some recruits, but that doesn't really count.
