MechWarrior Online that turned the game into a robust farming simulator... well, no. Why would you even think that? But it will bring a whole lot of other updates to the game as outlined in a new letter from the game's creative director, starting with improved team functionality and UI improvements. That goes along nicely with the addition of air strike and artillery consumables, allowing players (especially scouts) to bring down a little extra firepower in a match.
The development team is also introducing a new class of special 'Mech, the Champions, which are custom configurations that sport a permanent 5% experience boost. That's in addition to improvements to the game's overall performance and more community events for MechWarrior Online players the world over. So that's a no on farming, but a yes on several improvements that should make your days of stomping around in an enormous walking tank more enjoyable.
