Is combat mostly running up to things and clicking LMB over and over?
Could not completely tell you; I played with a bow, and it was very similar to Skyrim - press and hold to fully draw back, press and let go for a quick shot. You did have to aim, but unlike skyrim, it seemed relatively forgiving if you weren't exactly on point.
What I would LIKE to see is almost an amalgam of games - it'll sound weird but a mixture of Kingdoms of Amalur, Skyrim, FFXIV and GW2 would blend together really well, and still keep to the "fully customizable" spirit of TES. The skyrim part would be classless at the beginning, then leveling specific things. KoA would come in with, as you leveled, you would gain access to abilities. Depending upon how you spent those abilities would "class" you. Buy some stealth/dmg abilities, AND some ice magic abilities? Rogue/Mage type class - call whatever you want, Mage/Archer? (Arcane Archer, obvs). The FFXIV aspect would allow you to level up all things, but only "equip" certain things. You can still choose abilities that aren't PRECISELY your aligned spec, (ie, you can use cross class abilities you have already leveled, but only if they share an affinity and make sense - like a dps warrior type might have a threat dump that you could use on the rogue/age) but mostly you would aim for specific things, and you would be able to level everything on one character, then change it up. Go from a healer/heavy plate guy (cleric) to a healer/cloth guy (sage) for specific abilities, etc.
The GW2 part would come from the armor/weapons etc you equipped. You wear plate and a shield + longsword? That plate gives you dmg absorb, shield gives you some amount of crit immunity, longsword gives you parry ability. Plate + Shield + Mace? Same, Same and threat, no parry. Healer aspected? Plate + Shield + Scepter? Cleric.
Same class as above, but chainmail + Greatsword? Chainmail would give movement speed, maybe haste, and greatsword would give things equivalent to great cleave. Rogue/mage type? Dirk + focus crystal gives +poison dmg (From dirk) and force magic (from crystal). Rogue/mage with a dirk and stiletto? + poison from dirk, +parry from stiletto. (So you end up more of a duelist class rogue, who would use mage abilities to say, gain shadows or some crap.)
That might be too much work, but considering how many things you level in ESO anyways, something that you could customize down to the VERY SMALL ASPECTS would be phenomenal. Also I am a fucking whore for leveling shit up endlessly like a jrpg so come at me bro.
And also because I want a fucking plate wear rogue with two daggers like those god damn inkies in Nektulos that used to rape my human enchanter while doing the epic quest. Cleric guild, wtf r u doing.
