Dmitriy Kupriyanov, more famously known as LighTofHeaveN, is one of the most versatile DotA players in the world who played for Natus Vincere. He has the most tournament wins of any player in Dota history. He's also the most successful ASUS (LAN event held in Russia/Ukraine, four times a year 2007-2011) attender with his 12 (from 20 possible) first placements with many different teams, proving himself to be one of the best players in the world of Dota, especially in the LAN environment.
 Professional Career
Starting off his DotA career at SAY_PLZ, with his great farming ability already amazing players and audiences alike, he was soon the key player in SAY_PLZ. During ESL finals, Light's Silencer defeated TeamQ after 2 hours and 30 minutes after being a game back, and this became one of the classic matches in DotA. In ASUS Open Autumn 2007, SAY_PLZ defeated Zenith and VP on their way to the championship.
 Virtus Pro
The following year, SAY_PLZ became TeamQ, while Light joined Vigoss and co. in VP. However, in MYM Prime Defending #10, due to a lack of training, VP horribly lost in the first round. Light's Soul Keeper has become a symbol of the 6.5x version, being able to farm Boots of Travel and Radiance in exceptional time.
Controversially, after VP received Ks.int's sponsorship, Light and NS decided to head to Rush3D.
Right before his famous journey with DTS he attended Chinese LAN event "ADL 2009 (Alienware Dota League)" under the flag of RoX.KIS. The team consisted many Russian superstars and some of his future teammates (Dread and NS), but it was just a one time thing formed just for the event, which lasted for one month right before Christmas 2009. The team managed to take out many big teams from China during the competition (one of the reason was Chinese reshuffle being under way) and end up placing second, losing 0-3 to domestic XFY (also squad which was put together right before the League) in the finals.
In March 2009, Light decided to join DTS. Being one of the most versatile players in the world, Light is able to play any role from Support to Carry. In 2010's World DotA Championship, a surprise strategy including Pandaren Brewmaster, Enchantress, Lone Druid and Shadow Priest was able to defeat the then strongest team in the world, EHOME, as DTS eventually gained 3rd in WDC. After Artstyle and Dendi left DTS at the end of 2010. Light decided to stay in DTS, however, they soon lost the sponsorship.
Along with the remaining DTS members, Light joined M5.
After a few months with M5, Light was purchased by Na'Vi for the amount of $2,000 as a replacement for Goblak. He immediately produced results, winning ASUS Open Summer that year and took gold at The International and Electronic Sports World Cup 2011. LighTofHeaveN proved himself to be an extremely versatile player who could take on nearly any role from support and utility to semi-carry.
