I do not know what you've snapped at him. Mech just a little touch up and all would be well: simply remove homing in twin-Seekers and in fact he will be like Heat-canon. And Abilities leave such as it is - with the homing and high rate of fire.
I do not understand why everyone suddenly ass on fire? Are you afraid of the berserker that flies over the enemies? And into him Nephilim discharge the abilities? If you were on the ideal distance for Nephilim, then who is to blame? You blame yourself, idiot that does not know how to combat with other mechs. Why did not climb cuddle with Brawler?
Or you have forgotten how to use shelter and dodges?
In general I am disappointed not to narrow-mindedness and the desire to make the game something new. You remind of old grandmothers in the courtyard, who need only bench.
If perhaps I didn't lose customization on the other mechs this might be true but being locked into certain weapons, items, internals, and much slower dodge cool downs across the board (Scout withstanding) then I might agree with you that this isn't really a problem and something that could be easily dealt with.
BUT!
I did lose my choice of items, internals, and weapon choice on my mechs. I will find myself much slower with dodging and unable to avoid fire like I could before. When a C-Class mech has a nearly 2 second dodge cool down there isn't a great amount it can do against something that is fast, has a far quicker dodge cool down, has air dodge, and greater air mobility it isn't hard to see who has the advantage in majority of situations, especially with how open some of the maps are and were already open to Hellfire abuse.
This isn't just a double Seeker A-Class being added into the Hawken we know and love, this is a double Seeker A-Class being added as a real money purchase only and everything else is changing around it leaving players with far less options on how to counter something like this.
