Fidelity or Tolerance? (Warden Level Cap/PvMP Virtue selection)

Looking for second opinions!

For context, I recently Valar'd a Warden to 140 on my current "main" server (Grond) as I didn't want to organically grind a third one all the way to cap (my previous 2 are confined to US-based servers).

When it came to virtues I settled on Fidelity over Tolerance for the 5th slot, in part because the Warden has a relatively quick debuff-removal skill so I figured a bit of extra health would be more beneficial over the added resistance (Valour, Honour, Confidence and Loyalty being the others).

That said the current featured instance is The Ruined City, with one of the quirks of the 1st boss being an unclearable DOT that tiers up which can only be stopped if you manage to resist it... while I managed to brute force it in tank spec, I was wondering if uncurables pop up often enough in the later instance clusters (e.g. Harad) that it might be better to focus on Tolerance instead?

And that's without even factoring in Monster Player De-buffs/DOTS (which is a different kettle of fish entirely)...
