If you're going to primarily focus on using Corvus to complete content and/or focus on arena, then yeah go for it.

It's important to remember that suicides affect everyone and you can't use Corvus everywhere at the same time - looking over the rest of your roster, many of them interact very poorly with suicides due to their lack of immunities and/or their reliance on frequent use of special attacks. So if you're still spreading your roster across multiple game modes then you might find the ultimately hurting your more than they're helping.

If you have the units, you can try unlocking suicides, use them for specific content charges with Corvus, but then switch them back off again for other game modes (particularly AQ). This is expensive, however, and generally not recommended.

Corvus is great without suicides and a 4 star is good even in the uncollected monthly.
I wouldn't pay the cost unless you're pushing into Act 6.
