2017/10/16 ------------------ NOTES v0.987 ----------------------

--- engine

- changed SpringRTS engine version compatiblity and requirement from 103.0 to 104.0

--- new units

- added SPHERE hardened fission reactors
(this adds a choice between the previous cheaper but vulnerable economy clusters or sturdy ones)

--- balance / mechanics

- enabled "raw movement" (requires springRTS engine 104.0)
(this means units are more likely to travel in a straight line over short distances if they can)

- improved overall combat attributes of most AVEN, GEAR and CLAW commanders by about 10-15%
(they're no longer being overvalued relative to SPHERE commanders due to their cloaking ability)
- improved the relative balance between the underwater and surface weapons (underwater weapon is generally worth half as much on all commanders)
- reduced range by 6%, increased DPS by 12% but doubled the energy consumption for the unmorphed SPHERE commander's beam
- fixed issues when trying to aim the torpedo weapon while underwater (affected several AVEN and GEAR commanders)

- made cloakable units about 8% cheaper

- removed 0.1m/s and 0.2m/s and 50/100 resource storage from construction units and reduced the costs by roughly 10%
- construction aircraft build at the same rate as other builders of the same tech level instead of half, but costs increased by about 30%
- reduced construction aircraft movement speed by 20% but increased their HP by about 20%
(they're still fragile)
- increased build power of construction drones by 25%
- increased the build time for most level 2 buildings by 37% to have the resource drain consistent with the other buildings

- fixed aiming delays that made most fast firing weapons (emg, miniguns, continuous beams) deal 10-20% less damage per second than expected
(this happened while maneuvering or against mobile targets even if they were still within tolerance)
- fixed units with torpedoes trying to target enemy aircraft

- reduced CLAW "Grinder" dps and range by about 10% and cost by about 25%
- made CLAW "Mega" significantly bigger and stronger and adjusted the cost
- made GEAR "Cascade" bigger and increased the damage per pass, but now it deals M damage instead of H and is slightly slower and adjusted the cost
(a single bomber is now much more likely to be able to destroy a single factory or small cluster in one pass and survive)
- increased GEAR "Instigator" HP from 850 to 1000 and cost slightly and changed the armor type from L to M
- increased SPHERE "Crustle" HP from 1100 to 1200 and adjusted the cost (+6%)

- "Advanced Plating" upgrade changed from +8% to +10% HP

--- UI

- prevent sharing units to enemies
- tooltip shows build power for construction units in metal per second
(note that level1 factories are built 50% faster and aircraft have a builtin cost modifier of 7% less metal but 100% more energy to build/repair)
