Brainwright im sick of getting picked off at 500+ meters by Large Laser carrying mechs on open maps... so im not certain where you are getting the rendering range issue.
Really our only effective weapons require us to get in suicide range, ranges where not only do we have to worry about Large Lasers, but MGs, mass SRM launches from missile mechs, MRM swarms, splash from heavy Autocannons. Mechs have a TON of effective weapons against us, we only have a handful of effective weapons against mechs, most weapons that threaten us, also have a greater range than us.
