I just realized that Arcane and I kind of discuss balance a lot. Fancy that. PROPOSED CHANGES TO THE X-1 X-1 gains leveling bar. Akin to the current Reaper drone, with the difference being the bonus of 2.5% bonus movespeed and damage per level. The X-1 can only gain experience from kills it makes. X-1 Mk.1 and Mk.2 gain an "upgrade" ability. Said ability costs 100% of its energy. This ability upgrades the X-1 Mk.1 to Mk.2 and Mk.2 to Mk.3 without losing the currently accrued levels and level bonuses. This will incentivize players to keep the X-1 alive throughout the game and make microing it somewhat easier as a reward for not throwing it away. This should adequately address all current Combat Engineer issues. Players that lose their 'bot late game will be penalized, but able to accrue levels more quickly due to the presence of Overdrive and/or BHS.
