Rangers have low endurance (but high health) - so even in armor they tend to go down quickly when they get pummeled a lot and don't receive healing. The good thing is that your animal companion can always step in front of you. Since it has no health it's no so bad if it gets damaged badly or even knocked out.
So in general a ranger who wants to tank/offtank without goind down quickly needs high deflection. Ranger's starting deflection isn't too bad. So with a weapon and a shield and a ring of deflection and so on it should be ok if you don't drop RES. Maybe also put on a Blunting Belt, it reduces the damage of grazes even further without the slowdown of fat armors.
Another approach is to use the pet for offtanking and staying near it and provide constant healing so it doesn't go down like the Riptide build does (it's a 2.x build without WM content and abilities). This is a melee ranger with focus on pet damage, but I guess you can easily grasp how Shod-in-Faith boots are used to keep the pet alive.
Luckily, ranger's health is quite high despite the low endurance. So an approach where you don't have high deflection but constant healing works quite well if you're not trying to tank it all.
This can be achieved with things like Shod-in-Faith and Veteran's Recovery as well as items with healing bonuses (Belt of Bountiful Healing, Fulvano's Amulet, Maneha's armor...) and bonus from survival. This way you can achieve a lot of staying power while not gimping your damage dealing too much. This might lead to more resting though because low health might force you to. More CON helps here - or some potions of Infuse with Vital Essence (they will give you back health if you drink them before encounter ends). A Moon Godlike would be the most powerful choice with this approach, but any other race will also do. Human is fine, too. If you go this road then high INT and MIG are benifical since both regenration as well as Shod-in-Faith will do more healing (because lasts longer) with high INT.
INT can also be very nice for stuff like Stunning Shots (or using Borresaine with stun on crit) and especially Binding Roots. Those have AWESEOME base duration already but it gets really nuts with high INT and a crit. You can cause the stuck affliction for up to a minute with this ability, removing the need to tank the guy who is stuck. And it's 5 per rest - some folks think that's bad but actually it's pretty neat: in easy encounters you don't need it but in tough encounters you can easily pin five enemies in quick succession for 45 seconds and more - turning some tough bounties into a cakewalk.
As a backup for emergency situations you can give Takedown to your pet - it's quite nice as an addition to Binding Roots.
If you plan to use wounding weapons (Tidefall, Persistance, Drawn in Spring or Acuan Giamas) and also like Wounding Shots for pure damage then I would not go the "healing" way but push MIG to the extreme and drop INT altogether and maye even put on an item with a malus to INT (Dandy Hat of the Deseased Yak -1INT or Ultimate Hat of Alluring Perfection -2INT) because those woundings' overall damage (25%) gets increased by MIG but doesn't rely on INT at all. It just gets strechted over time by high INT. Low INT on the other hand leads to nearly instant appliance of the whole wounding damage which can be awesome.
It works quite well with an Island Aumaua with Arms Bearer talent (= 4 weapon slots): You pick up two arquebuses, Persistance and a weapon + shield. Usually you would fire with Persistance and watch the awesome wounding enchantment do its magic. But once you have to take out some enemy immideately you switch to arquebus and use Wounding Shot (it's devastating with low INT and arquebus). If the enemies are not already dead you switch to shield and tank a bit.
There can be some very different approaches how you want to solve your issue. If you want to use a bow a lot and don't like to offtank too much but just want to stop attackers I would use high INT and MIG with Binding Roots instead of high deflection and RES.
