No. Here's a bit of reference to aid you:
1. Relequen set will provide you approximately 9% damage
2. Backbar Nirn set will provide you approximately 6% damage, plus Haemorrage procs (hard to judge with bear of course) that should be 2-3%.
3. Medusa will provide 6% damage if you have 100% crit and 125% crit damage, the absolute MOST it brings to the mix.
4. Kjalnar, the monster set I'm mostly wearing, provides about 5-6%. I haven't tested Zaan much for comparison and Stormfist is only on my hybrid tanks so it's not worth comparing.
Already you can deduce that Medusa is useless versus Relequen or Nirn. Whorl is comparable to Rele, around 8% or so but I have less experiencing remembering the numbers since only my Templar wears it atm.
If you don't want to farm/use fancy sets, then do the following:
1. Equip Back-Alley Gourmand
2. Equip Order's Wrath
3. Equip Stormfist monster set, since it's so easy to obtain
4. Give up with Maelstrom and DEFINITELY give up Master's staff.
For the cheap/starter setup you can give Back-Alley Gourmand and Order's Wrath a try.
Gourmand and Wrath combine to grant you 16.3% crit and 21% crit dmg, plus 258 spell dmg. If you get 20% from animal companion passives to crit dmg you're gonna be looking at hitting 65% crit, 100% crit dmg (before barbed trap). If you wore the Kilt on top of this you could be 75% crit, 125% crit dmg with trap out. Is it top damage? No, you'd be better off wearing Whorl of the Depths and Pillar of Nirn, but it's better in overland and easy dungeons where burst beats longevity.
