As some one whos main was a lvl 80 grenade engineer before swapping to a Guardian, Grenade kit isnt all that its cracked up to be (unless of course your under water when it becomes a godlike ability). Tome of Wraths Aoe spam is at least instant... tossing grenades out only to have the enemy move out of the way as your grenades take 2-3 seconds to land is infuriating. And you have to be a mind reader to predict and throw to compensate accordingly... even then 90% of them miss. Solo its even worse, better to run bomb kit and stick to em like glue in my opinion.
One thing ive found that made the difference in 'Fun' with my guardian in WvW was finally crafting most of my Exotic set and getting lvl80 and some cheap 'Rare' lvl 80 weapons, really helped in both group and solo fights... and im a Consecration/Virtues Guardian that uses Cleric gear. That being said there was a spot around 60 to 70 where I felt really gimped for some reason. Despite that I feel like im contributing to those around me... only wish people would stop panicking and evading out of my damn ranged Sanctuary when I drop it on them.
I think half of my problems in WvW is that very few people actually know what guardians do so it comes down to me having to work around them rather than others working around me and wasting a CD, which is probably why a support Guardian is better in smaller groups.
