yes i started to play regulus a lot and i just love him, also my style was always to hit from 90 yards away 
i mostly use snipe/mines build since i can just put huge dmg with mine fields at flags and snipe isnt only useful for killing an enemylow health demigod if u have a lot of mana u can continiously use it and hit anyone u can see and help ur allies. Also team with 2 regulus is insane.
My build
first take immidiately teleport scroll and move immidiately to the second most useful flag so u can capture it easy depented on which map u are(at caratract go for health flag for a health advantage) when u take it u can use a flag lock(optional) and then go to the xp flag since its the first most ppl go to take. Best is to first take scroll and teleport and in the middle time u can buy a favor item(prefer blood of fallen since helps for survability) then take snipe as first skill. It is really difficult to catch a good regulus without warpstone so u ll almost never need to spend money on potions. The items i use for this build is first collect 1750 to buy the 1750 worth helmet(this will make things a bit more easier for u to use skills) after that collect 1500 and buy the 1500 worth helmet then u will have almost unlimited mana until a lvl. Then u can just spam snipe at every demigod u see without any problem, then use 8 mines at a flag and put a totem so if u see anyone coming and touch the mines, ready a snipe and if he falls on all mines he is 90% dead. Also when ppl start to realize u are using mine fields they will not move close to flags so u are like invenaruble if u stand around ur mine field. Other skills i may use is gadget device or scope to take out towers. Other items are 1500 worth armor and maybe a warpstone(but snce it will be removed u can buy seed boost items). Also mark of the betrayer can be really good to slow down a enemy quick and do some dmg.
I like the angel build but it may be a bit costly and not so safe since u have to be a bit close until u take scope. For that build good items would be
poisoned dagger(favor item) or the rapier that gives attack speed and 250 health.
then Wyskmin Gloves
a helmet so it can keep up angel fury
3300 worth gloves that give 10% for 2xdmg
but i mostly use snipe/mines since i a very safe and i only need to go close if a demigod has very low hp, Also spamming snipe on tower and demigods is always good since with 2 helmets there is no problem on mana
