They really don't.

I play a Galscout and having 6 module slots seems a bit too much. With 5 Slots, I'll still be able to equip 2 complex precision enhancers, 1 complex range amplifier, 1 complex profile dampener, and a complex KinCat. Any extra modules are really not necessary.

The same applies to the extra equipment slot. If I want to use a cloak, then I should be able to equip only that. However, if I feel I can do my duty as a Scout and be just as effective without a cloak, then perhaps REs would be more beneficial to me. Being able to cloak and use other equipment seems a bit greedy, especially when the game already has a class dedicated to equipment use.

From what I have seen, the addition of these slots has encouraged many players to opt for brick tanked builds as it is now easier to obtain 700+ eHP on a Scout suit. They indeed have become the more effective Assaults, now with the added bonuses of higher speed, more CPU/PG, lower profiles, smaller hit boxes, better suit passives, two equipment slots that allow them to cloak and self-rep through hives, etc.

Alone, brick tanked Scouts are easy enough targets for any eWar built Scout to handle. However, 6 of them with cloaks and proper comms have the ability to zerg rush an entire team and keep their opposition at bay.

Remove their extra module slot and their HP will drop by 100 or so. Remove their second equipment slot so that Logis become more relevant in matches.
