I agree the Dragon is an ambush Mech, which sould be played quiet different.
Compared to scouts you have much better movement ability in my opinion. This means climb up hills like nothing or hovering over rocky roads without taking leg damage like a light mech.
Further in my opinion, large rang capability might be fun - but not effective. This Mech is designed to be fast... a hit-and-run heavy Mech. Having 4 laser in its arms the FLAME is maybe the best option for precision aiming at high-speed.
Most people have terrible heat-builds... check my personal favourite Dragon build:

Very good heat handling capability, focused damage especially for close combat on scouts (where most normal lasers just "slide" over all Mechparts) and max. speed... with some dmg-pushing and crit-seeking srm.
Once get used to hide-hit-run and circle close in different loops around slow turning atlases or stalkers... this mech is not only very fun... its quiete effective.
Equal builds can be managed with normal Dragons... you may try 2xsrm4 and 2 large pulse laser on a DRG-1N... but having 4 equal lasers in arms, opens new possibilities in combat (you can push arm-aiming-angel while holding Ctrl key, still be able to steer normally).
Dragons are very effective if you can behind the enemy for example... so either they turn and your team shoot their back while you dance around... or if they do not turn... you will melt their backs, which are weak... sometimes very weak in armour.
Best results of course, are provided if you have a mate which helps you to raise firepower in their back, confuse them whom to shoot at, or to protect you with ECM...
A Dragon which is played "normal" as maybe a Catapult will be dead very quick... it has a reason why its designed to be hard to hit in side torso (to avoid XLengine be cored quick) and have the highest speed for its class... its ment to be played different.
With dual basic skills and speed tweak it´s hell of a fun... but whatever you do... watch your heat management. A shutdown means losing arms or death most time.
