I currently ride 8 speed Campagnolo group, and an upgrade to something more modern is not a bad option, though I have found used 10 speed 105 group locally for decent money, I'm even more intrigued to buy it.
I guess 11 speed chain is not as durable as 10 speed? After all, it is thinner.
I'm not racing so going 11spd is not really important.
11spd on the other hand is still a mystery around here, road cycling is not developed and LBS's don't carry spare cassettes or chains, so maintenance is purely internet webshop related.
As for plastic thing, I suppose shifting is not as "harsh" as with 1st gen Campagnolo where you need really to have strong wrists for shifting. If it's easy clicking, it won't ever fail. That's one of the reasons I want to upgrade.
I don't need to use my wrists to shift, I can use my pinky to shift the plastic part and only need two fingers for the aluminum part.
Where are you getting 11 speed isn't as durable? I haven't read of any durability issues from Ultegra 11 and Dura Ace 11 or Campagnolo/SRAM 11 speed products.
The wear and tear on a chain is not on the sides and it doesn't stretch as some may think. The wear is on the pin that the teeth of the crank/cogs tensioned on. That wear and tear likely will remain the same regardless if it's 11 or 10 speed. The teeth spacing far as I see are the same between 11 and 10. If you have a lot of wear on the sides, may want to get your bike retuned? The pins should wear before the sides do for replacement.
