BAP is not worth the space it takes up on an LRM mech.
First, a few facts: http://mwo.gamepedia.com/BAP
That is the current iteration of the Beagle Active Probe. now, of note here are a few things.
- it counters 1 ECM within 150m
- it extends lock range by 25%
- 25% decreased target info acquisition time
the second point is what i here people quote wrong a lot. BAP does NOT decrease lock time. it decreases the time it takes to get info on a target. i've lost count of the number of times someone says "but it decreases lock time!" no. you're wrong. it is a nice plus, but again there is a module that does it if you want it
Now, the big one! it counters 1 enemy ECM! within 150m
150m. 30m sorter than ECM's Disrupt range (180m). it is also inside LRM minimum range (180m), so we can not use our primary armament against ECM mechs within range.
Against fast ECM mechs (lights, the CIcada) you will not be able to keep out their range. so, on their way to you you will pass through 30m of ECM disruption to any lock you had. when they get inside 150, you will counter them but be reduced to using backup weapons to try and scare them away. so even with BAP im stuck shooting this Spider with some mediums, maybe a large or some streaks. terrific. if you do scare them off, they will jam you again for that 30m difference.
i could also choose, when i start countering, to continue with my business of LRMing something else, which leaves my back open to the light mech. taking defensive maneuvers makes it VERY hard to keep an LRM lock up, because you must stay pointed at that target. again, the BAP makes little difference as either im dead or not completing my primary task while im back to waving my lasers at a light.
against a D-DC, either you can keep range and use something like a TAG to counter his ECM, or you've utterly failed and have an atlas within BAP counter range and are probably a sack of scrap.
the ONLY time bap is nice is when youre stuck within 150m of an enemy ECM mech that is not moving, and you cant move either. then and only then is it nice. a not moving ECM light will probably die to your teammates shortly, an ECM atlas can be outrun.
that is why i no longer carry a BAP. it is so situational that i just cant justify it. instead of a BAP, take a TAG, or more ammo. just stay with your teammates. that light wont be able to hug you and shut you down with friends nearby. that D-DC was never really able to rush you anyways if you positioned yourself properly.
im sure there are many of you that disagree, how useful do you all find BAP?
