Well, the competitive community is massive and much bigger and active than the offline community, so they don't need to appeal to offline players and they never intended to.
The purpose of the LE versions is to be included in online cups and tourneys, sometimes even LANs. Some of the cups include prize money as well. Last year there were about 6 or more cups in all kinds of modes (iCTF, CTF, TDM, Assault, Siege, Duel). One of the cups managed to raise $2000 prize money, and it had actual paid sponsors as well.
LE maps need to have flawless gameplay flow, making paths for their map is basically wasted work for them. That's because they need to put all of their effort and energy in balancing the map properly, so it can be accepted by the competitive community and played online pretty much every day for years. Otherwise, if the gameplay balance is even slightly off, their maps (like mine) won't be accepted and never played or included in cups. LE maps needs to have the PERFECT gameplay balance and it is not an easy thing to do, nobody will care if your map is pretty or not - It can use a single texture and basic lighting trough the whole map, but as long as the gameplay is balanced it will satisfy everyone.
