Barring X-Ray Lasers , use of normal optic Lasers in Arenas is practically non existent since mid 1990s . Laser Reflective Plastic Armour is dirt cheap - as are Hot Smoke Smokescreens , HDSSs , Hot Smoke Dischargers & Chemical Mines . Often completely derails Laser using Player's tactics - especially in tight Arenas .

Plasticores are ESPECIALLY usefully against single minded persistent Tire Shooters . Three linked VMGs , HD Ammo & HRSWC (plus good Gunner skills) , will shred a Solid Tire & 10pt Wheelguard if two or three of them hit well .
Fortunately 'some' of these focus only on your Tires & not at your (very) thinly Armoured sides . So the silly person is often trapped into shooting at your Plasticores , behind 10pt Wheel guards AND 10pt Wheel Hubs , through half an inch of Smoke - ignoring your 15-20pts of vulnerable Plastic Side Armour .

Then almost crying when you set them on fire , blow their Wheels off with TDX mines ... and then seeing the paper thin Armour on your designs after the game ...
( ... good times ... ;-) )

Any player can take you unawares by a Player using a Laser armed Design unexpectedly - once .
They will then face Anti-Laser vehicles for next 5 to 10 Games ... until they 'learn their lesson' ...

One weapon or linked set of weapons , made accurate with SWCs or better , one or a few light Drop Weapons & as much as possible wrapped in extensive Component Armour is almost standard in Divisions 7.5 to 30 . Div 5 budget vehicles can be very innovative . Div 40 and above can be ... strange , overpriced & very often not particularly effective .

Big Guns rarely rule in Arena Combats - unless two so armed vehicles gang up on you at once , and your unable to fight back properly due to HC & Targeting accumulated Damage Hazards etc .

Hope this helps .
