Regardless of weight , speed or number of jumpjets, any mech with a single jumpjet can climb a surface of any incline or height by repeatedly tapping the jumpjet button. Because the forward momentum is applied nearly full force at the time of pressing the jumpjet (instead of forward momentum being applied gradually in the air linear to the upwards thrust). I can get a victor with 1 jumpjet to the highest point on any map. Buildings are 90 degrees up and so are still unclimbable but anything with less than a 90 degree slope can be climbed with a single jumpjet using the tapping technique. The tap climb can be used indefinitely, as you tap you constantly are forced forward and up in small increments and the JJ recharges fully between each tap, so you basically spend nothing (fuel wise) to climb a massive 85 degree mountain slope in your 85 ton mech which has no momentum and 1 JJ.
I think the solution is simple, as I said above, less forward thrust on initialization, more forward thrust the longer the JJ is held.
