As a rule trial sets, that is sets you obtain from participating in 12-man trials, are only useful for PvE. You can be competitive in PvP using only crafted and / or tradeable (overland) sets. However you will probably want the following items long term:I will probl take my time soloing as much as possible, but in the long run i intend to do pvp. Can i get competitive by making my own/buying gear, or must i do the trials/raids to get best stats?
If you PvP solo or in small groups, stamina builds perform better relative to their magicka variants with the exception of magsorc and possibly magplar. If you play in larger groups it shifts to a more even balance. In general stamina builds tend to be rounded fighters, whereas magicka builds have more (group) utility or excel at special purposes, such as bombing. If you want to play a healer you will also very likely be a magicka build.I plan to play as a necro, though Im not sure what route is "best" in terms of pvp in the end.
Leveling and endgame are different. You can always respec from one to the other, although your race may favor either magicka or stamina. Magicka specs often level more easily, because you tend to unlock self-healing skills earlier or you gain passive sources of off-healing. I don't know whether this is true for necro, though. If you go the stamina route, enter Cyrodiil and do the intro quest. No need to PvP. You will obtain a stamina self-healing skill called "Vigor", which you probably want.Maybe just go a magica build?
Nope. I would not level as a tank. You need to kill stuff and your aim is to heal while doing so. Questing / overland content is also so easy, you don't need to be a tank. Down the line, the role of a tank in PvP is either a group role or that of a troll. Being a PvP troll tank that "can't be killed" is not all that easy, but you will always be killed eventually and do little killing yourself. If you get a kick out of how long you can hold out against players swarming you, fair enough. You may have trouble with NPCs that you can only kill very slowly, though. NPCs in Imperial City and some parts of Cyrodiil are a nuisance as a (pure) tank. If you look at experienced players surviving against multiple opponents in PvP, they are almost never an outright tank. They just know how to play. Line of sight, e.g. using obstacles to your advantage, is the #1 survival tool for classes that lack mobility, such as necro. They may build somewhat tanky, but they aren't tanks as such and even squishy builds can survive via LoS.Tho i see some tank builds also looking tempting, at least for lvling.
