I've started wanted a supercarrier with these new changes... They look much more interesting to fly now. I could afford one, but I couldn't afford to replace it.... so I'll stick with Carriers for now 
Some alliance mates used theirs the other day, got the second Titan kill since the patch, it dies so quickly. They engaged a enemy capital fleet that clearly hadn't had their ships refitted for the changes. The Titan had a fraction of the EHP it would have had pre-patch due to lack of plates! Buffer on the carriers and dreads without plates is low enough now that 2-3 Nags/Phoenix will potentially alpha through armour/shield on a average fit
Also, Solo PvP Titans are a thing:
