Right now the balance is this:Not really fair comparisons.
What I meant was that a Scarab can already drop foot soldiers within 1-3s. Giving the Scorpion the same capability wouldn't really change the game that much.
Scorpion: stronger, can easily take out heavier targets like goliaths but struggles against infantry at long range.
Scarab: fragile, cannot easily deal with heavy targets but can take out infantry at range.
Your question is basically:"Is it a good idea to remove the only drawback of the Scorpion?". Well, not really. I would assume that to most people "sit outside of a settlement and slaughter everyone and everything with impunity" isn't very good design anyway. Right now the Scarab and Scorpion complement each other, both have weaknesses and uses. An 'excellent at everything' vehicle is going to be problematic at best and frustrating at worst.
