Mechcommander 1 featured the 'Heavy Flamer' - a rather large weapon that could do significant burst damage at short range. The theory behind this was that the flamer was less of a conventional flamethrower and more of a plasma cannon, venting a burst of superheated plasma from the mech's reactor. Flamers in Mechcommander 2 did damage to enemy units - and a pretty significant amount of it - but were horribly gimped by massive heat generation.
A weapon that causes heat on the enemy target alone and does little else fulfills a very small niche in the game. It would barely be worth classifying as a weapon - more like a piece of slightly useful tactical equipment.
I would like to see the MWO flamer follow Mechcommander 1, and exist as a useful brawling weapon. It should not be useless against any mech, regardless of their heat management capabilities. The fact that it applies heat to the target should be a purely ancilliary function.
Flamers should do less DPS than lasers, or perhaps weigh more and do similar DPS, but the rate of fire should be low. Low enough to justify large bursts of damage as opposed to the faster recharging and more sustained damage of lasers. Personally, I'd like to see a stream of fire for 1 second or so, mimicking the short damage-over-time of other energy weapons.
Remember that lasers flash-melt or flash-vaporize things on contact as a method of doing damage. Technically, this should apply 'heat' to the mech, but it is apparently not a statistically significant amount, even among spectacular laser barrages. Even a white-hot jet of superheated plasma shouldn't interfere too greatly with heat dissipation.
What is good game design and what is historically accurate are not always the same. Mechwarrior Online is a game, not a Battletech historical documentary. As such, game design comes first.
TLDR: The primary objective of a weapon is to do damage. This model works for a reason. Flamers are weapons - and first and foremost, they should do damage. Any other effect they cause (heat) should be purely secondary.
