Would you rather have the Frost Destruction Staff kept as a tool for Tanking, or instead converted back into a tool for DPS?
Note: There
might be some bias here since I really do not like Frost Staff tanking. Keep that in mind. What I write here is all true though from my experience and anyone I have played with except for the speculation at the end.
Before the Ice Destro became a tool for "tanks", it used to be pretty common amongst Magicka builds, and especially Nightblades since it fit them well thematically. Many players wanted (and still do want) to create an Ice Mage DPS build. It was a fun alternative to using a Fire Staff despite losing a small bit of damage. The main drawback was a DPS loss on Wall of Elements which was not a very big loss, and made the Ice Destro fine to use for essentially all content. A Warden class featuring Ice-based skills was highly requested for this very reason. For the time being (prior to Homestead), playing a Sorcerer or a NB with an Ice Staff was the best choice for an effective “Ice Mage” DPS build.
In terms of DPS:
Homestead launched. Both the Fire and Shock staves were simultaneously given passives to increase their DPS while the Frost Staff was instead given tanking passives, so it was dropped from DPS builds completely. Using a Flame or Lightning staff yielded significantly more damage
and group utility, as well as not requiring you to take points out of a valuable passive (also losing lots of DPS) unless willing to risk taunting on an accidental Heavy Attack. Though uncommon, it is not unheard of for a DPS in group finder dungeons to slot Frost Staves because they want to play Ice Mages, not realizing they taunt enemies/bosses on Heavy Attacks which cause either them or their tank to get kicked.
In terms of Tanking:
The 1H/S is still far superior for tanking, which does make sense for someone wielding a Shield. No one in endgame PvE uses a Frost Staff tank….at all. The extremely rare exception may happen once in a long time during a non-score run, but this is only meant to take screenshots and troll friends. It is quite literally unused. In PvP, there are maybe a few decent players per server who use them who aren’t just zerging with 50+ people (in which case you can run around with your fists and do well), but are ineffective at best. It is highly, highly uncommon, rarely ever seeing any use.
Magicka is too valuable when tanking to spend blocking, and nothing else besides two passives support a tanking playstyle with a Frost Staff. The Destruction Staff skills themselves are meant for damage dealing – never tanking. There are way more passive tanking 1H/S benefits which are all far stronger, and the 1H/S active skills are essential to playing a good tank. Frost Staff tanks are highly ineffective and constantly kicked from dungeons because the only players using Frost Staves are quite bad as tanks and don’t have the tools to even do their job well.
Wrobel and Wardens – why things probably turned out this way:
The Warden's Winter's Embrace skill line was directly changed into the tanking/mess of a skill line it currently is due to the concept of Frost Staff tanking, which also directly corresponds to Wardens being terrible at DPS.
This was Wrobel’s response to Warden skill lines in the
Warden Developer Q&A Article located here……
"Question: How important was it to ensure that the Warden is able to perform multiple roles (damage, tanking, healing) from just their class Skill Lines?
Wrobel: This was a pillar of the class's design. ESO: Morrowind is a great opportunity for new players to experience The Elder Scrolls Online for the first time, so we wanted a class that was easy to pick up, yet difficult to master. When we came up with the ideas for Animal Companions, Green Balance, and Winter's Embrace, they each had to fit into one of these molds. We did move some of the Skill Lines around as we were designing them to see what best fit. For example, we were playing with the idea of having Winter's Embrace exclusively deal damage, but when trying to make an entire class' Skill Lines, the other options made less sense for a tanking tree. There are only so many abilities you can make out of mudcrab armor!”
……To put it simply, the design of forcing each skill tree to perform one role (which strays from all other class designs) likely caused them to rework the Warden’s Winter’s Embrace skill tree, which is essentially a parallel of a Sorcerer’s Storm Calling and a Dragonknight’s Ardent Flame, into a tank skill tree rather than a DPS skill tree. The Frost Destruction Staff was then dragged along to fit the tanking concept too. Either that or the other way around - Frost Destruction staves were decided to become a tanking tool, and Winter's Embrace and to follow. Those are my thoughts on that at least.
