I've been taking a look at the light armour/magicka focused possible ability builds for dragonknight and sorcerer and it seems the sorcerer classes spells are at a disadvantage to DK's regarding pvp in terms of damage and self-healing, if we were to imagine a 1v1 between the two. (I'm talking more specifcally about a solo situation here rather than looking at group battles)
For example crystal shard has a cast time allowing for interrupt, dark exchange has a duration to cast( restoring magicka also I know) while dragons blood is instant, as well as DK's Draconic Power having passive abilities which greatly boost healing and seem to outweigh the magicka cost reductions/regeneration that Sorcerers passive abilities have a lot of. I mean, if it were somehow an extended fight between the two those passives/restoration of magicka would of course become more useful.
Encase immobilizes for 3.5 seconds but deals no damage until upgraded to deal damage or to snare. While dark talons immobilizes for 3.5 seconds, also dealing damage, and can be morphed to reduce enemies damage by 15%.
I can't argue with most of storm-calling but even so, these are just a few examples, if you take an in-depth look at DK's class abilities/passives vs Sorc, it appears that DK has a significant advantage in this kind of situation.
Have others come to the same conclusion for magicka focused characters in pvp? I'd be happy to hear any info that shows otherwise, i've been trying to convince myself to start with a sorc, just need some guidance as I've played DK more in the beta. (sorc only to lvl 12 while DK to something like 22)
Thanks for any input.
