What is the time frame from where you are getting this advice? From most recent? Or posts laying around for some time?
Most people believe in firepower over survivability. There is a point to this, as if you can deal enough damage in a couple of hits, you can kill them before they kill you. The other half depends upon not being shot back as much as you shoot out (hide among other higher priority targets, such as the assaults, or attack from odd angles and flanks). An XL engine lets to do this better, at better speeds, at the cost of being easier to kill.
I personally don't recommend XLs on anything heavier than a light mech, depending upon the mech and the build. A Crab is iffy with XLs, if you know what you are doing. A Grasshopper (heavy mech) loves XLs because of how hard their side torsos are to reliably hit and destroy. On the flip side, a Wolfhound can work with an XL, but actually likes LFEs much more than an XL...
For Crabs, I strongly recommend anyone who wishes to be more of a linesmen (not flanking, sticking to the team, and wants to take a few hits) to take a LFE or STD engine. Due to it's CT and HD hard points, there is strong merit for a STD engine in a Crab, but sometimes you need some weight so a LFE is a reasonable choice. If you are relatively newish to the game, than avoid an XL on your Crab for the moment. As you get better, you may end up feeling more confident in your abilities and may revert back to the XL at a later time.
Honestly, I find there are rarely any "wrong answers" when it comes to mech construction. A lot of it depends upon what you are expecting out of the mech, what role you are intending to play and how much of a risk you are willing to take. I'm a low risk taker, so I don't like using XLs unless I either have/need to or I'm light enough that it isn't as much of a risk because of size and speed. Some people like to go high risk to try and reap the largest rewards, or know how to mitigate that risk by the way they play.
If you want to have more survivability, try to switch to a LFE instead of an XL. As long as you keep at least a 250 engine rating, it should work out well for a Crab. That's reasonably good speed, with ten built in heat sinks (which are better than externally added heat sinks).
Thanks, the builds are mainly from mechspec and Baradul's vid. But I totally get your advice and I'll look at the LFE instead. Any recommended build? Probably I should stick to ERLLs for the moment?
