As a counter to the above point about HLC and predator vs. high ps pilots, why does rex need an HLC? Try him with just predator and use the 60 points you have left to field something else awesome to go with it. I like Rex w/predator, Fel w/PtL, and Jax w/PtL. Joust with Rex, flank with Fel and send Jax into the midst of your opponent and watch them squirm. I will tell you that with even re-rolling just the one die, you get 4 hits at range 1 more often than not, and almost always 3 hits at range 2-3. This leaves you free to crit them to death with your focus.
This is similar to builds I like to run normally, high PS, few upgrades, KISS, thanks! I'll have to try this!
