Oh man do I ever.
The champ of “looked down upon but I still like it” has to be my Wraithknight. I modeled that thing really well and I painted it nicely, too, I want to show it off! Doesn’t hurt that it’s a jump gargantuan creature with a melee Destructor weapon and lots of stomps to kick over people’s main battle tanks. >.>
Howling Banshees are regarded as pretty useless. I maintain that they’re not bad, they just aren’t competitive with the rest of the badass options in the Eldar codex. But I usually field a squad of 9 on foot anyhow, just because they’re a useful dancing bear for people to pour all their anti-infantry fire into. This leaves my windriders a freer hand. Alternately, if people do ignore the Banshees, they tend to charge something and make it into beef stroganoff. So that’s fun.
The other guilty pleasure models on that score are probably my Stormraven (gets shot down alarmingly often for something that’s usually transporting my warlord, my most expensive squad, AND a venerable dreadnought) and my venerable dreadnought. Poor old Dread Brother Vannheim gets popped nine games out of ten the very turn he shows up and lays down the heavy flamer/assault cannon pain and he so rarely gets to actually charge things… but he really wants to get closer to the enemy and SQUISH them in his huge metal fists. And whenever he actually does get to smash something, it makes the game SO MUCH more fun for me, even if I lose. Because Vannheim got to CRUSH something.
