Lance strider

You want lance strider that can hold it's own at close range?
Try paladin

Though in all seriousness there's quite a few issues here. The main issue is that this strider takes the bad parts of lance and cranks them up even more. Charging while on hold fire is a cool mechanic, but it is horrible because not only does it create a lot of micro, but it also gives the unit potientially infinite alpha. Any strider could just suddenly get wiped off the map by an instakill laser without any form of counterplay to be done, because the lance could be deep within enemy porc. The main counterplay would be to spam shields, since their health actually scales enough to take on the lance strider, which encourages the shield spam that makes pots so cancerous even more

Note that cereb is 2.5k, less than every strider but athena and ulti. the heavies non strider arty, tremor, is 1.6k, and 2 lances is 2k. there isn't really much space between traditional arty and cereb that you can fit in a strider
Hitscan Alpha also counters mobile units a lot more than the giant pot shieldballs (who are countered by either shield pen, which lasers are incapable of even at starlight levels, or continous saturation dps, which this unit is not). Units will slowly get attritioned by hitscan alpha while shieldballs can tank the alpha as a whole and match the lower dps of hitscan with their regen more easily

we can further nerf it, so if hit with paralysers, it malfunctions and explodes... so its then couterable with silo para, and the boom is proportional to the charge level
