Elegon is a complete joke. On hc he is a total wimp with nearly no more difficulty than normal - but on normal he is just... Nah not doable for most average players.
Problem of most Pugs is that most of them are casuals knowing LFR or have maybe a 2/6 4/6 guild for some brighter days. You could easily do DS 8/8 with them but not MGV or HoS. You might be able to kill some bosses but that's it. No more doing the Karazhan. Bad thing for altoholics like me who have mates with rl who don't want to raid with 3 different chars per week.
I have to guild hop to actually get my alts ready. Guilds with potential and 1-2 raid-days are rare. Most of them are new founded and I might help them out till the time they want more than I myself. Casual Guilds wipe forever on certain bosses and you cannot help them in any way. Best thing are organized twink raids from ~top20 realm guilds. But even those have gotten rare on my realm.
